Topic: 562t door lock/unlock

I took off 712t key less entry and installed 562t RS to my 2003 camry.

- Blue wire from 562t connect to Blue(unlock) wire of my vehicle.

- Green wire from 562t connect to Blue / YELLOW(lock) wire of my vehicle.

These two wires from my vehicle work with 712t but don't work with 562t. I can't unlock the doors, anything else works fine. Do I need extra relay for lock/unlock door ?

Anyone have any idea to help .

have you programmed the unit for double pulse on unlock? and is the plug for the lock/unlock wires plugged into the correct port on the unit 562T?

yes, I checked the wires and programmed for double unlock pulse so many time. After programming I also hear two clicks from 562t when I hit unlock button on the remote.

Can you physically ground the wires in the vehicle and make them lock/unlock? if so, are you sure you dont have the blue and green wires from the 562t backwards? remember, they put out a positive pulse as well opposite the negative pulse when locking and unlocking. try switching them and see what happens.

I switched them and the result is when I push the unlock button the doors is lock, nothing happen when I push lock button on my remote.

Thanks for spend time to help Ckeeler. My 562t module maybe get defect at some point of programming. It programming light does not flash to indicate the change to duoble pulse. I changed to the other 562t of my friend and then program to double pulse then it work. I got the bad 562t that I ordered from www.electrocnicsbonanza.com
