Drove off without the smart key, now the LC wouldn't start, help..

[MUDIMOND]

The title says it all...
Later was able to get the smart key but without luck, there is current but no response whatsoever, the start button doesn't react either, the vehicle is just dead..
Unplugged and reconnected the poles after an hour, still nothing, any help would be appreciated.

Has the Smart Key been in contact with another vehicle's transponder key? It may be malfunctioning.

or, have you tried the "emergency start function" (if the "Engine Start Stop" switch can activate ACCESSORY mode)?:

Owner's Manual:
1. Set the parking brake.
2. Put shift lever in "P".
3. Set the "Engine Start Stop" switch to ACCESSORY mode.
4. Press and hold the "Engine Start Stop" switch about 15 seconds while depressing the brake pedal firmly.

Have vehicle checked by Toyota dealer.

BigDouggie,
Thanks, unfortunately the start/stop doesn't do much, wen pressed it only shows some Japanese text on the center part of the cluster which I don't understand but the green/orange light on the start/stop button doesn't come on.
If the transponder theory is correct using the second smart key/remote should start it, correct?

If the transponder doesn't work, don't you just hold it up to the start button and press it? It is designed to work without battery at short range.

JBHorne,
What a day, it seems the smart keys/remotes are working, light comes on.
The engin starts only using the remote starter but everything remains the same, locked steering wheel....
Once connected to an OBD the error came; "B2289 immobilizer key timeout", couldn't reset or clear the code.
Unusually, I had both transponders in the car (and remote start), one on me and the other in the center console, it has been like this for few days, working fine, not sure what was difference in this case...
Local Toyota dealership may not be capable of helping, may have to bring in an expert from another territory, will see..
Any thoughts..?
Thanks,
MD.

Why couldn't Toyota have made it easy to reset the engine immobilizer like simply placing a smart key within range again?!

 

[MUDIMOND]

Gentlemen,

Any idea on what exactly is required/used to reset the engine immobilizer?

Do you think that we are necessarily going to need a Toyota expert using their Techstream devise or it can be done with a good OBD Scanner used by any knowledgeable technician?
I ask as my situation is unique, our local Toyota dealership doesn't bring in Land Cruisers mine was imported individually from Japan..
Or maybe the procedure is standard across the Toyota range which they carry normally.
Also this info will help me determine who to contact from abroad to come in and do the job..

Please see attached below some relevant pics of the in-cluster screen Japanese message, OBD error code and the worst part; The Cruiser being carried on a flat bed truck

Mind you I'm still puzzled as although I thought that I drove off without the smart key, there ware one present in the vehicle all the time!!?

Your opinion would be appreciated

MD.

Gentlemen,
I'm happy to report that the LC has decided to start the morning after for no apparent reason, now, I'm even more anxious to understand what went wrong and how did it fix itself?
Thanks,
MD.

Did you pull the battery for 20 minutes? I believe the manual says that's a potential fix.

Also could you not just start it with the key right next to the button? The manual says that as well...

JBHorne,
As indicated earlier, I unplugged and re-plugged the battery poles for at least an hour, didn't work, not immediately but the day after.

Are you referring to the mechanical key being able to start the engine, how?

Can the vehicle reset itself, over lets say 10 hours?

Thanks,

MD

 

[JBHorne]

I'm referring to holding the smart key right up next to the START button while pressing it. The manual indicates that if the smart key dies, this is the method to start the vehicle.

With a key in the center console, there shouldn't have been any problems. This concerns me a lot. I drive in subzero temperatures in Alaska in the middle of nowhere, so a malfunction like this could be deadly to me. If I can't start the engine, I'd become a frozen mummy in no time.

Could you please clarify where exactly was YOUR key when you started the truck? (not the key in the center console).

JBHorne,
I understand but immobilizer keys seemed to be working (LED) and both couldn't become damaged/faulty at the same time as both do open and start the vehicle now, I know I can be unlucky but not that unlucky

When you say "immobilizer" key, you are referring to the Toyota Smart Key, correct?

It looks like this, correct?

Also, are they keys GENUINE Toyota OEM, or eBay knockoffs? Did they come with the vehicle new or are you trusting that they are genuine?

Also, how do you have two keys present at all times? I have this problem with my wife. She has another one of my keys in her purse. Sometimes when we go somewhere, she will leave her purse in the car. I am able to lock the vehicle with my remote (not the button on the door) and since the smart key remains present in the car, I cannot unlock the car via the handle but bust use the remote.

So my question is how do you always have two keys present? It was my understanding that a key should not be left in the vehicle as this could cause problems. Hence, could this be the "timeout" since one of the keys was present for too long?

Again, on page 481 of the manual it describes how to start the vehicle if there is a problem.

JBHorne and planetalaska;

Puzzling, yes I use only the original keys that came with the LC, mine doesn't have the red button though, it is a JDM thing.
No I don't normally keep both keys with me/in LC all the time, this was just a mishap, the way it happened; one key (K2) was mistakenly forgotten in the vehicle for one week and then my wife had the other key (K1) in her purse in the LC, I dropped her off and conteniued on driving for about 90 minutes, parked the car, realized that I didn't have the (K1) not realizing the (K2) was in the center console, had someone bring me (K1) tried to turn it on and it wouldn't start, total shut down.
It sounds like interference between the two keys if any, really not too sure.
At the time, I tried couple of methods, non worked but the remote starter, it turned the engine on but nothing else.
Regards,
MD.

This actually makes sense. The key that was left in the vehicle caused a timeout in which the system stopped responding to the SmartKey operation. This is by design to prevent the key from draining battery. When a connection to the vehicle is established, there is considerable battery using for that period.

I strongly believe that holding the key up to the start button would have allowed the vehicle to start. Actually, follow the full procedure on page 481 of the manual. If you do not have a PDF version of it, send me a PM with your email and I will send it to you.

 

[MUDIMOND]

JBHorne, Regarding draining of the batteries, you mean the K2, the one that was left in for about a week, correct?
Anyway, I'm relived to know it isn't a more serious fault without explanation..


================

planetealaska, I hope JBHorne has answered your questions and concerns, what do you think?

JBHorne, I garage my 08LC200 for 3 months in the summer with one smart key left in vehicle. I can't remember a time when after coming home I could not start vehicle. Are you saying that the auto start might time out after so many hours if a key is left inside vehicle? If so, do you know for sure how many hours after key is left inside vehicle the time-out occurs? Or does the time-out only occur if two keys are left inside vehicle?

leaving 1 or 2 keys in the car for a long period of time will not cause an issue. When I am armoring out TLC 200's I leave the keys in the center console for the first 2 days and then the last 3 days or armoring (takes a total of about 8-9 days for me to armor the car)

Personally I hate the damn "smart key" it causes nothing but troubles for me in my line of work. Many of the places my TLC's go have ECM protection so that has to be turned off before you can start the car. Also on the higher end versions VXR/Lexus that credit card key causes interference - you hook the computer up it comes up as bad antenna. And I can not lock or unlock the doors, and while the lights are flashing cause of the locks clicking away you can not start the car.

I have seen it form time to time you start with K1 and drive off - and you remove the key (normally a light will come on the dash) but K2 or the credit card key is in the car and you then shut it off. You cant start it with K2 until you bring K1 back to the car. - but please note this doesnt happen all the time (otherwise if you lost your key you would never be able to start it again)

and being a JDM - you can buy the watch that is also the smart key.
