Hello everyone, I am happy to report turning over my bruiser to the best in the area. David (aka Tardwrangler) from Urban Land Cruisers in Atlanta, Georgia just finished an evaluation of my truck. It is in GREAT shape and just needs some hugs and kisses to make it happy again.

Somethings we talked about even he had no answer for.

The first one is my glass on the truck. From the front doors to the sliding glass, not the windshield or the rear gate glass has sand etching. The etchings run down the base of the glass for the front and rear doors, then on the sliding glass it curves up one side and down the bottom. The word "LAND CRUISER" is etched in as well. I have never seen this before, and neither had he (he knows his stuff...bless him) which made me nervous. I don't want to lose this glass in a stupid off-road incident (Shoo-happens) and not be able to replace it. Has anyone seen this before?

The second one is the TDS "alarm" system that came on my truck. This was a mid-90's dealer add-on. It is an ignition kill switch and a TDS logo'd key fob to open and close the doors. The switch is mounted someplace in the vehicle that upon activation causes your car to be unstartable. What it also does is remove some of the standard features of a Land Cruiser like doors lock when you have the key in the start position, and unlock when you pull the key out. I want to remove the TDS system and have it go back to factory. My soon to be wife will be driving this soon...and I'd like the doors to LOCK each and every time.

David said he was going to ask Cruiser Dan (parts poomba) about these, but anyone with information leading to the answer is more than welcome to post. This just blows my mind.

I own the service manuals and none make mention of the TDS system and I can't seem to find much about them from dealers. I would have done better talking to my florist about it than that guy. Too bad these things never fail, because Toyota Techs (for the most part around me at least) seem to forget that Toyota makes these things. Their salesmen don't....oh no...they remember everyone they $old.


Here is the part where I praise URBAN LAND CRUISERS of Atlanta. For almost nothing he looked my truck over from stem to stern and gave me a summary on his company letterhead with prices and opinions. Then he and I talked on the phone and he walked me through the recommendations. I emailed him what I wanted (quite a lot of work.) I could do most of the things he is going to do for me...but there is a certiain amount of satisfaction having it done by an experienced technician the first time.

I really enjoyed working with David, and I am sure that Cruiser Dan will like the parts order coming to him from them. Haha!

Toyota didn't make your alarm. It was installed at the port by the distributor; most likely Gulf States Toyota since you have the TDS (Theft Deterrent System) made by Audiovox. For example, the RS3000 alarm used by many 96-97 FZJ80s distributed by TMS USA was made by Fujitsu-Ten and installed by some guy at the port in California.

I believe I have the manual for your TDS alarm but don't get your hopes up as the manual sucks. Very basic stuff as I recall. I will have to look for it tonight so remind me in a few days if you don't hear back from me in this thread.

Please elaborate.

With no alarm system installed, a "factory" 80-Series will *not* lock the doors when you have the key in the start position. The doors will not automatically do anything. They also will *not* automatically unlock when you pull the key out.

It is not clear to me whether or not you believe the "autolocking" is a standard feature. "Autolocking" is a customizable feature of the RS3000 alarm system. It may be a feature on your TDS system but I would have to read up on that.

So unless I'm misinterpreting your post, you do NOT want to rip out the TDS system if the "autolocking" is a feature that you need.

... Later ....
OK, found the TDS manual. The switch on the DS kick panel is the valet switch. When this switch is ON, the "Autolocking/Unlocking" feature is activated. It appears that "Autolocking/Unlocking" is disabled when the valet switch is OFF. It also appears that there is no other configuration available (unlike the RS3000 alarm.)

I have a 96 LX450 and I have the option to have it unlock the doors when the ignition is turned off and it will lock the doors when it is started again. I dont have one of the add on security systems, just the stock key-less entry.
good luck.

Hmm....
 
Mine has a problem wherein unless locked before turning the key the doors will not stay locked (they unlock) if the lock/unlock button is pushed after the key is turned.

I think this is part of my Room lamp control relay issue but am not sure.

I believe you have an add-on system for keyless entry. Perhaps the SecuriKey system? Is this system described and documented in your LX 450 owner's manual or in a supplement?

I may be able to identify the system if you can post a picture of your fob.

Most everyone that replied to a previous post I made said their doors auto-locked somehow, and auto-unlocked somehow. I am lead to believe that this was a standard feature in most of the 80 Series. I could be wrong, but then again...these things are like lego's and no two seem to be identical.

Here is what I want regardless of the how/if/when

1. Doors to lock when the key is turned to start.
2. Doors to unlock when the key is removed (turned to off)

I do have that switch on the kick panel, but the lass I bought this from said all hell broke lose when she flipped it on accident. So, I don't really feel obliged to testing it until I know what it does. I told this to David (Urban Land Cruisers) and he said he would look it over.

All I want is a keyfob that opens, locks, and panics and doors that autolock/unlock if it is possible. Heck, even my little DD locks the doors when I put it in drive.

I thought that if I can't get this to work, I will figure a way to put a switch in the shifter that toggles the locking at least. You know what they say...where there is a will there is a way. I just hate having extraneous junk in my truck that sucks. The keyfob that comes with the TDS system (I only have 1 fob) really sucks. It only has 1 button on it, and that button does everything. You have to click and hold it for anything to happen...and go in order of the 3 operations it can perform.

Hold 1 : Doors lock
Hold 2: Doors unlock
Hold for a really damn long time: Panic

Also, I understood that this was a dealer installed option, or as you called it a port installed option. I am down with that, I just needed to know where to cut the module out of this thing. I want my truck returned to STOCK electrics.

Thank you for the replies thus far, this is beginning to be really informative!

This is the thread that I replied to, and is the first time I heard about the "autolocking" feature at all. If it is a seperate alarm install feature...I would love to hear more about this doo-dad.
 
If the fob is junk anyway, you should just install a new keyless entry/alarm system with the features you want.

These are fairly simple to install, and if there is already one on the truck it's practically an R&R (I know because I replaced mine myself). Any competent stereo shop could do this in a few hours.

This is exactly what I did. I got a Viper alarm/keyless entry system for 80.00 and had it installed for 100.00 it has three buttons (lock unlock, aux & panic) and works exactly as you desire.
 
I am lead to believe that this was a standard feature in most of the 80 Series. I could be wrong ...

You would in fact, be wrong. All theft deterrent/keyless entry systems for the 80-Series were either port-installed, dealer installed, or PO installed. I will add that I don't have an LX and I have not seen the LX Owner's Manual so I can't say definitively that the LXs were not built by Toyota with some type of keyless system. However, I have been maintaining the "LC vs LX differences list" for a few years and that has never been mentioned as a difference between the LX and the LC.

If anyone has an LX OM then post up those pages that describe the way the "autolock" works and I will update the LC vs LX section.

Your TDS system will not do this as far as I can discern from the manual. (I will add it to my web site next week. It needs to be scanned and the copy that I have is very poor quality)

Your options are aftermarket or custom build.

The switch on the DS kick panel is for valet mode. Of course, the PO may have rewired it to do something else but if you have a "stock" TDS system then that is what the switch does (as I described in an earlier post.)

I use the Toyota manual posted around here somewhere when programming my FOB. I bought a replacement FOB through Cdan for my Lexus as well.

Ken,
You have 2 LXs; 96 and 97. Is this "autolock" described in the Lexus OM (Owner's Manual)?

The RS3000 alarm manuals that I think you are referring to came from Fujitsu-Ten and getting them was a real biatch. Christo offered to host the manuals on his web site because, at the time, my web host wouldn't permit large files. Now they allow large files so the manuals are on my web site and also on the Slee web site.

The lexus manual says if you unlock and don't open a door in 30 seconds it will lock again.
 
I have a 97 LX450 and the complete operation of the keyless entry alarm is described in the OM. I recently referred to it to enable the auto door un/lock feature that Proven is looking for. There are also programming choices to autolock and arm the truck after you exit and close the door, as well as setting off the alarm if you don't insert the ignition key soon after disarming and opening the door. Not a disireable option for me when I am dealing with a 2 year old and bags of groceries!

The Lexus fob is part #08191-60820

I will scan the OM pages relative to the alarm and send a PM to Beowulf
 
-B- both my 96 LX and the 97 LX I took apart have the RS3000 system, it varies slightly from the Toyota RS3000, the fobs have the Lexus logo on them, also the wiring to the pizeo under the hood from the drivers kick panel is part of the factory harness instead of port added like on the LC, the harness from the unit under the seat to plugs in the kick panel and up to the GBS/LED were separate from the rest of the wiring,

I do not know if the alarm was factory or port installed but I do know the truck was at least prepped for the RS3000 alarm during manufacture because of the integrated pezio wiring


here is the text from the 96LX OM. auto lock/unlock in bold at the very end


THEFT DETERRENT
84
THEFT DETERRENT SYSTEM
To deter theft of the vehicle, this system is designed to
sound an alarm and keep the engine from being started
if any door is opened while the system is armed. An
alarm will also sound if window glass is broken or if
power to the system is interrupted then restored while
it is armed.
When triggered, the vehicle’s horn sounds and the exterior
and interior lights flash in a unique pattern. Perhaps more
importantly, the vehicle’s starter is disabled at the same time,
preventing engine start.
Arming the system
1. Turn the ignition key to the “LOCK” position and
remove it. (The system will not arm it the key is left in the
ignition switch.)
2. Exit the vehicle and close all of the doors. (The
system will not arm if any door is open.)
3. Push the transmitter’s top button.
At the same time the “Theft deterrent system” arms, the
doors will lock, the tail and marker lights will flash once, and
the buzzer will “chirp” once.* Also, the vehicle’s interior lights
will come on for 3 seconds**, and the status monitor’s LED
will begin to flash steadily.
After using the transmitter to arm the system and lock the
doors, you must use it to unlock the doors and disarm the
system. Otherwise, the system will be triggered and an
alarm will sound.
Note: Manually locking the doors by key outside the
vehicle will not cause the “Theft deterrent system” to
arm. The “Theft deterrent system” can only be armed
and disarmed using the transmitter.
4. After confirming that the system is armed (tail and
marker lights flash once the buzzer “chirps” once), you
may depart from the vehicle.
Never leave anyone inside the vehicle when you arm the
system, because opening a door will cause the alarm to
sound.
* If a door is open when you push the transmitter’s top
button the “Theft deterrent system” will not arm (and the
doors will not lock). Instead, the buzzer will sound for up to
10 seconds or until the open door is closed securely.
** So long as the interior light switch is set to the “DOOR”
position.

When the system is armed
ALARM TRIGGERING
While the system is armed, the alarm will sound and the
vehicle’s starter will be disabled under the following
conditions:
If any of the doors are opened.
If the window glass is struck and/or broken.
If power to the system is interrupted (for example, due to
a dead battery or a blown fuse) then restored.
After about 1 minute, the alarm will automatically stop and
reset, but the vehicle’s starter will remain disabled until the
system is disarmed.
ALARM TRIGGERING BY THE GLASS BREAKAGE
SENSOR
A specially tuned microphone is mounted in the status
monitor next to the LED. This microphone is tuned to detect
the sound of tapping on or breaking of the vehicle’s window
glass. The sensor has been specifically adjusted by the
factory for your vehicle.
The glass breakage sensor triggers the system in two ways:
1. When the sound of tapping or breaking of glass is
detected, the system will first sound the alarm 3 times as a
warning.
2. If the glass is tapped on or broken within 5 seconds of the
first detection, the system will trigger for about 1 minute.
REACTIVATING THE SYSTEM
After the alarm has been triggered, the system will reset
itself. The alarm will sound again under the same
circumstances as listed in “Alarm Triggering”. Once armed,
the system can be triggered and reset 10 times and the
alarm will sound. After the system has been triggered 10
times, the alarm will no longer sound, but the vehicle’s starter
will continue to remain disabled.*
* After disarming then arming the system, the alarm can
sound again.
STOPPING THE ALARM
Push the transmitter’s top button once.
The alarm will stop, the doors will unlock, and the vehicle’s
starter will work again.
OR
Insert the key into the ignition switch, and turn it to
“ON” twice. (“ON” " “LOCK” " “ON”)
The alarm will stop, and the vehicle’s starter will work again.
Note: Pushing and holding the transmitter’s top
button for more than 2 seconds activates the Panic
Mode. For additional information, see “Sounding an
alarm (Panic Mode)” on page 9.

Status Monitor LED
The status monitor’s LED gives the following two indications:
FLASHING – The system is armed. You need the transmitter
to disarm the system and unlock the doors.
OFF – The system is inactive. You may open any door.
Testing the system
1. Open all of the windows.
2. Arm the system as described in “Arming the
system”.
The doors lock, and the status monitor’s LED will flash.
3. Open a door from the inside
The system will be triggered when the door is opened and
the alarm will sound.
4. Push the top button on the remote control
transmitter.
This will cancel the alarm.
5. Repeat steps 1 through 4 for the other doors.
If the system does not work properly, have it checked by your
Lexus dealer.

KEYS
Master key – The master key works in every lock.
Subkey – The subkey will not open the glovebox.
Key number plate – Keep the plate in a safe place
such as your wallet, not in the vehicle.
To protect things locked in the trunk or glovebox when you
have your vehicle parked, leave the subkey with the
attendant.
Since the doors and trunk lid can be locked without a key, you
should always carry a spare master key in case you
accidentally lock your keys inside the vehicle.
If you should require replacement or additional keys for any
reason, contact your Lexus dealer.
You should also put a copy of the key number with your
important papers.
Insert your flat key in its key case as shown. We recommend
that you always carry this with you as a spare. Do not leave
it in your vehicle.
NOTICE
Do not let the key case become bent as the key may
fall out or become bent also.
The flat key is designed for emergency use only, so
do not use it regularly instead of the other master
keys.

You have 30 seconds to open a door after using the remote
unlock feature. If no door is opened within 30 seconds, they
will automatically re–lock, and the “Theft deterrent system”
will re–arm.
*If the doors were locked without using the transmitter, you
must push the transmitter’s top button twice. The first time
it is pushed, the “Theft deterrent system” arms.
**If the tail and marker lights flash 3 times and the buzzer
“chirps” 3 times, this indicates that the system was triggered
and the alarm sounded while you were away from the
vehicle.
Turning off the buzzer
The factory setting for the buzzer’s operation is ON (the
buzzer “chirps” when the doors are locked and unlocked).
When the buzzer has been turned off, its operation is

Good to know Raven. I'll update the list of differences to note that the RS3000 was standard on the LX (or at least that all are prewired for it.) If anyone has their original window sticker or a brochure, it would be good to know if this alarm was a standard or an optional feature.

-B-
 
So that explains why some people considered this the default. Good to know...now...to figure out how to switch mine over.
