Toyota corolla verso 2007 . the central locking
Toyota Corolla Verso - Central locking has just stopped responding
So you don't waste your time, here are some assumptions: -
1. When I press the key fob there is no sound of doors trying to lock/unlock and I know the key fob is fine.
In this situation reset the alarm/locking system
Below is the procedure I followed to get the central locking working again: -
Open the passenger door, and look at the side of the dash board. There should be a triangular panel. Pull the panel off to reveal a small set of fuses(see the back of the panel for the fuse map). To power down the central locking you need to remove the Dome Light fuse, this is located top left. Second one down 7.5 amps. (if in doubt remove the top two 7.5 amp fuses I did)
When you remove the fuse(s) you will notice the interior light go out indicating you have powered down the system.
Now leave them out for at least 30 mins so any capacitors can discharge properly. (Be aware while the fuse is removed all central locking is disabled, so the other doors are open. I left the fuse(s) out over night with all the doors open but I don't recommend it, 30 mins should be fine)
After 30 mins replace the fuse(s) close all doors, and then try your key fob, hopefully you should here that satisfying locking sound.
2. When I press the key fob I hear the locking system trying to engage.
This could be a faulty door switch on any door including the boot, or there could be a dent in the inner door panel of any of the doors, usualy the rear doors due to the seat belt not retracting properly.
Check all door switches for damage, and check inner panel for dents, just a small dent where the switch connects can be enough to not engage the switch. This will stop the central locking.
Use some kitchen roll wrapped in tape (as a makeshift pad) and tape to the inner door as a temp measure to engage the door switch. At least you can then lock the car.
