Faulty Lock

[celica_xr9145]

I have a problem with the drivers side door lock on my 91 AE101 Trueno.

It has central locking so when i lock the car via the drivers side, the passenger side door locks aswell.

Problem is that the drivers side door will not unlock (key doesn't even turn) which means to get in i have to unlock the passenger door and climb through and unlock it from the inside.

When i try to unlock the car via the passenger door, the passenger door will unlock but the drivers side door will still stay locked.

You can lock it by using the drivers door and both doors will lock but can't unlock.

Any ideas on what the cause of the problem will be?

I was thinking there was a loose cable but not so sure.

Hit the previous owner up about it and ask him how he unlocked it with a seemingly faulty drivers door lock.

Hit the previous owner up about it and ask him how he unlocked it with a seemingly faulty drivers door lock.

What he does is unlock the passenger side door, climb through and unlock the drivers side from the inside. Apparently its been like it for ages.

What he did say was that not long ago he had his key cut and the new key opened the lock for a while then broke again

The key seems to be fine, not bent or anything.

Am picking up the spare key this weekend so maybe that will work for a bit.

Hmmm

Well if its the lock thats faulty (i'm just going to throw ideas out here, none guaranteed to work)

Options may include,

Swapping lock barrel from drivers side to passenger side (probably different part, but who knows)
Buying another lock barrel + key off another ae101 and putting that in.
If you could get a whole set of locks that would make it easier as you could just change to the new keys and hope for the best. Otherwise carry both new and old keys with you. new for drivers / old for passenger side / boot.

I'd be taking the door card off first anyway, do both sides, and check for anything broken, compare drivers side to passenger side for any differences etc.

Somewhere to start anyways.

Get a S/H drivers side lock and rekey the lock for your old key.

try a squirt of crc or wd40 into the lock first, then pull your door card off and have a look at thow things are working. It's amazing how many cars we see thru work that have "lock issues" that are supposedly caused by a car accident that only left a scratch on their bumper, but when we take off the door card you can see that someones been playing around in there before and put something in backwards

a common issue I've found on some is the little (usually white) plastic clip on the back of the lock barrel gets put on backwards and the connecting rod ends up at an odd angle and doesn't work as it should.

are you sure its the lock barrel, not the lock mechanism/actuator?

I have a problem with the drivers side door lock on my 91 AE101 Trueno.

It has central locking so when i lock the car via the drivers side, the passenger side door locks aswell. (do you mean via the inside switch?)

Problem is that the drivers side door will not unlock (key doesn't even turn) which means to get in i have to unlock the passenger door and climb through and unlock it from the inside.

When i try to unlock the car via the passenger door, the passenger door will unlock but the drivers side door will still stay locked.
(does central locking work via th passenger door? ie can you lock it from passenger side)

You can lock it by using the drivers door and both doors will lock but can't unlock. (so switch won't unlock passengers door? or neither door will unlock via switch?)
Any ideas on what the cause of the problem will be?

I was thinking there was a loose cable but not so sure.

need more clarification
begining to sound as if your central locking system is fubar

[celica_xr9145]

When using the drivers side door lock, you can lock it and the passenger side will lock aswell. But when you try to unlock it, the key won't even turn.

When unlocking via the passenger side door, you can lock it and the drivers side will lock too. When you unlock via the passenger side door, the passenger door will unlock but the drivers door will still stay locked.

Another thing that i have noticed is that the handle on the inside of the drivers door doesn't stay flush with the door panel. Will take a pic to explain it better.

Once i finished waxing the car, i'll remove the door panel and take a look.

Have tried WD40 but no good.

Thanks again

its common that the passenger side will unlock and the drivers side will not unlock if the key is turned on pass side.

If the drivers side lock actuator is fubar, test by sitting inside the car and testing the locking mechanism within the cabin.
Test: lock/unlock - drivers side/pass side = process of elimination

if the lock mechanism works inside the cabin via the lock/unlock switches on the door handle, then the barrel is indeed fubar. if not, then the actuator is poss fubar.

to get to the barrel, you have to take off the door card and have a 10mm spanner to take off two nuts that hold the door handle in place and undo the control arms that go between the handle and door lock mechanism.

If you have the control arm disconnected between the handle and the lock mechanism, also test the barrel again to see if it is indeed the barrel that can't turn.

If you ask a locksmith to do it, then it will cost the labour of getting to the lock/handle mechanism. If you just take the barrel in with the key, then its a lot cheaper.

[Mr Revhead]

ok, yeah sounds like the problem in in the drivers door, as mentioend above by others probably to do with the wee levers/clips.
The inner door handle points towards someone having been in there before.

everything else sounds like normal.

[DeeCee]

well to me it sounds like someone has tried to take the car by popping the drivers lock and damaging the barrel. If the lock/unlock mechanism works from pass side, then the actuator mechanism is fine. the barrel prob just can't take the key hence why no worky on drivers side.

I know that one from having to repair a couple of locks and actuator mechanisms in doors over the years.

[Lurkin]

Using the key on the passenger side does not unlock the drivers? my ae101 levin is like this as well.

Using the key to unlock on the drivers side but does not unlock = fail.

take it apart they are pretty straight forward / cheap at a wreakers. have a few spare lock barrels about - let me know if you want one via PM (easier to take to the lock smith to get aligned for your key ~$15 + 30 seconds @ the locksmith?)

does it look like the lock has been tampered with from the exterior?

[celica_xr9145]

Thanks again for the replies.

Removed door panel and from the looks of it the key barrel has had it. It could be possible that someone has tried to break in as it's in pretty bad shape .

The barrell itself is jammed, all the other components seem to be ok, will pop down the wreckers next week.

Thanks again
