RX300 Flat Battery & seized Door Lock

[Delphius1]

Just before Christmas i came home from two week's holiday to a car with a flat Battery and no central locking.

Access was a problem as the key had never worked in the door unlocking the car, only locking it. Turning the lock barrel to unlock the door was prevented. So getting at the bonnet release was initially impossible.

However, lots of penetrating oil and working the key between lock and unlock eventually got the door lock to work in the unlock position.

So it seems the lock barrel can work in the lock position, but be seized in the unlock position, which I've never encountered in a door lock before. 

Just for info, in case anyone else is in the same position. Penetrating oil and effort can get the door open so you can open the bonnet to charge the Battery.

I've found Deblock to work well at freeing and lubricating a seized lock ..

+1 for Deblock oil.
