Most car alarm and stereo installers may be able to help you. I took apart the driver's door lock on one vehicle, removed the tumblers and reassembled it but eventually someone messed with it and I was stuck

from what it sounds to me is that the alarm is still in anit theft mode
i had this happen to my vehicle
one thing you can try is lock all the doors try and unlock from the passenger side make sure that all the lock come up to the top where they should be
then try it
if that does not work then lift up the rear of the car like it was being towed and it should reset the alarm
short of that you will have to have alarm shop come to you

It sounds like your remote needs a new battery.
Your user manual should tell you what type... else, remove the old battery and find an equivalent.
Hope this helps... Good luck.

Okay you may want to check to see if the sensor on door lock cylinder hasn't fallen off from the lock itself. Pull of the door panels and check the wires at the door lock cylinder. Hope this helps.

you need to reset alarm/immobiliser.lock car with remote, hold button down for 30 secs,then press/hold down unlock button,should reset.another way is with key in ignition/turned on, press alarm button down and hold for 30 secs.this resets immobiliser.toyota
systems vary..depending on market.

A seized up door lock actuator. You can try freeing it up by spraying a good penetrating oil, my favorite is PB Blaster. If it wont free up you will need to replace it.
