Will door still work with key if code changed

The code is for the electronic lock only, and the door lock will open. If this is an ignition key, the code needs to match in order to start the vehicle.

Need to know how to recode the keyless lock system on the door

I have a 1988 Lincoln Mark VII but this still should work.

You first need to enter in the code you have. Then, within five seconds press the 1/2 button. Then, within five seconds of each other, press five buttons in any sequence you desire and this will be your new code. Hope this helps.

Power door locks do not work at all lights flash when remote is used to unlock doors. automatic lock feature does not work Once manually unlocked, sliding side doors work ok. tail gate can be used to opens...

the reason the locks dont work more then likely there is a code stored in the bcm for a lock output circuit normally caused by one if not both of the sliding door acuators. even if you change the acuators the locks still will not work until the code is cleared.
