Replacing door and ignition locks in 80 (1 Viewer)

[DestinationLost]

Hi all

First of all, new on mud. Just bought a '95 HDJ80 wich requires a good bit of TLC.

I removed the passenger side door lock to try and clean it, as per this thread:

Door key lock won't turn

How does one fix a door key lock? My drivers side one suddenly will not turn to the lock position. I was out of town yesterday, and the wife needed to use the 'cruiser, then phones me that they key is stuck in the lock after she unlocked the truck. I had some graphite lube in the garage and...

However, having removed all of the old gunk, the key still won't slide in without considerable help (no pun intended).

Considering buying a new set of locks online, as it seems pretty straight forward simply replacing the entire door lock (don't know about the ignition).

Does anyone have any experience with this? Did it work? for how long ?

OEM is significantly more expensive and having drained my toy-account on the rig itself considering something like this:

Sounds like you may have an old worn out key. Get a new key cut at the dealer based on the VIN.

No experience with the ebay link you posted, I pony'd up and bought a new OEM set. The link you posted does not have the rear hatch lock, which would be a no-go for me.

The ignition replacement is not hard. Just have to take the dash apart.

So I talked to three different Toyota dealers here in Denmark today. All three said that simply changing the locks won't work, because the car has an immobilizer system wired to the ECU. They all quoted me about 200 usd for a new key cut for the VIN which will match the original immobilizer. I'am gonna order one tomorrow which should arrive sometime next week.
i cleaned one of the door locks and though it still doesn't work (probably due to worn key) it slides so much better. I'am hoping that a new key will fix this.
Apparently all cars sold in Europe after 1995 has to have an immobilizer.

I don't see any "immobilizer" function on THAT key. Any place for a battery to reside?

You can buy a replacement set from a used vehicle and get the ignition, as well as all doors if you would choose to do that, but then you cannot get a new key without THAT VIN number if you choose to go that route.

It is an RFID like chip, not something that requires a battery.

If it were me I’d have the current key duplicated first to confirm if the car indeed has an immobilizer.

I'am a bit currious as to why you don't think the car has an immobilizer?

1) Three indenpendent Toyota-dealers told me so
2) By EU-law, alle cars sold after May 1996 has to have an immobilizer (I thought mine was a '95, but it's a '97). See link.
3) I can see the small diode in my car key (you can actually see it poking out in picture no. 2, although it may be a bit unclear).

Link to legislation

Hope this can help anyone with a similar issue in the future.

Anyway, I ordered a new key. Talked to a mechanic at one of the shops who's also into Landcruisers, so I got it for about 100 EUR which seems fair imo.

Alright. So I got the new key from Toyota, and thought I would write a small guide on how to clean door locks. Couldn't find it myself, and perhaps others will run into the same issue as I did.

1
Remove door side.
I had to remove 4 screws and unplug all of the plastic pins.

2
Gently remove the top corner of the plastic wrap.
Un-do the roads that connect to the lock and door-handle.
Then unscrew the door handle by removing these two 10mm bolts

3
Remove lock from handle. 1 screw and one 10mm bolt
(se photo above)

4
Unhook cylinder from housing.
Start by removing the small E-metal spring clip around what appears to be a screw.
Note: It's not a screw. Don't try and use a flat headed screwdriver. See result below.

5
Remove cylinder from housing.
Remove the two protective rings (one black and one metallic) from the external part of the cylinder.

6
Insert key into cylinder and pull cylinder out of housing.

7
Remove all pins and note exact position.
Note that each pin has a small number engraved.

8
Clean cylinder and pins.
I left it all overnight in warm water and dish soap overnight.
Used an old toothbrush to clean it all in the morning.

9
Let it dry for a day

10
Assemble and use graphite powder to lube it.
Remember the small spring at the end of the cylinder inside the housing

As a former toyota dealer, that is indeed a first gen immobilizer key. The thickness clearly identifies it as such. Where you having a problem with the ignition or door locks, or both?

the advice on having a cheap key cut off the vin code would have helped to isolate the problem for a few bucks, and would be handy as a spare to access the interior, without starting the car.

Nice job on cleaning and rebuilding the cylinder!

The ignition worked fine but I couldn't open any of the doors. This was probably partly due to dirty locks and partly due to a worn key. A new key and a thorough cleaning and everything works.

Will probably have an extra key cut without the RFID chip at some point, but having two keys with functioning RFID chips saves me a headache, should one key go missing.

Nice job on cleaning and rebuilding the cylinder!

Thank you.

My drivers side door lock has been dangling down inside the handle for a bit now. Based upon the above pictures it's a good bet that one or both of the attachment point on my door handle are broken. (much less likely that the lock core housing broke right?). I've been letting it go because I wanted to do window runs and sound deadening at the same time. But now it looks like I'm on the hunt for a door handle.
I appreciate the thread and the pictures.
