Unlocking doors with key

To arm content theft alarm.
1. Open the door.
2. Lock the door with the power door lock switch or
the remote keyless entry transmitter. The
SECURITY light should flash.
3. Close all doors. The SECURITY light should go off
after approximately 30 seconds. The alarm is not
armed until the SECURITY light goes off.

If a locked door is opened without the key or the remote keyless entry transmitter, the alarm will go off. The headlamps and parking lamps will flash for two minutes, and the horn will sound for 30 seconds, then will turn off to save the battery power.

Does it lock or unlock with the switch inside? When you try the keyless do you hear any noises from inside the door?

-If the problem is that keyless remote does unlock or lock door, but the lock lever still move when pulling up and down by hand. Door still open and close with both inner and outer, then might the driver door lock actuator is bad. The actuator lock and unlock the door for you when using the keyless remote or door lock/unlock switch.

-if you try using the key to unlock door and the key doesn't turn the door cylinder, then you have a bad door lock cylinder.

-if the lock lever doesn't move up or down and you can't open door using any handle, then you got a bad lock latch assembly.

I'm not sure what the issue is but hope this helps you.

spray locks with lock spray

Get into your passport and unlock all doors. Leave drivers door open. Put key into ignition. Turn to ON (not start), then OFF three times within 5 seconds. Close and open the drivers door twice. Turn key to ON then OFF 5 times within 5 seconds. Close then open the drivers door. Press either the lock or unlock button on the remote. Doors will lock then unlock. Press the button again. Doors will lock then unlock again. Close door to finish programming. If it doesnt work, try it again but turn the key faster. You have to do it all pretty quick, but I had it done on the second try.

usually after opening the door you can deactivate the alarm by pushing th unlock button or simply insert keyy in ignition and turn it on.

the door lock actuator is defective, they get really hard to move when they go bad, that is why the difficulty with the key.
