Key fob will not activate anything. can't unlock/lock car, no auto start, no truck unlock. Plus the interior door lock buttons don't work

Opening the door with the key should turn the alarm off. It is the certified way to get into a car if the key fob remote fails. Get a local auto locksmith to get you a new fob and key and program it. Keep the old one as a spare key.

Sounds like your auto locking/alarm system is out of sync with the buttons on your key fob. You will need to reset it so the fob buttons match what they should do. You will need to go to the alarm system manufacturer for directions on how to do that.

When a door lock is active intermittently it can be a couple of things. (1) The door lock actuator can be a the point of going bad.(2) The Key Fob unlock button can be bad and you have to press it several time to work OR if it is unlocking the door by itself at time a sticking button can cause this issue as well. Hope this helps and have an awesome day. If you like visit my auto repair website here: http://www.bigasautorepair.com/

1. Bad ground or connection at one of the door lock activators and/or switch. 2. Bad relay. 3.A loose or bad connecting door button (the plastic button in the door jamb that tells the car that your door is closed, it usually also activates the interior light. 4. Your key fob might have a problem. I had a Taurus where the key fob had a very small loose piece of wire in it and it caused the connection inside to conduct, thus activating the door lock when the key-fob moved in my pocket. Take the batteries out of the key fob. Does the door still lock and unlock?

Replace the battery on the key fob! Also, it may need to be reprogrammed by the Dealer!

We have the EXACT same problem. Can anybody help with this?

Insert key into door barrel or ignition lock and turn key, whilst doing this press the unlock/lock button, the led on the dash should flash to indicate this has initialised the key to the car, then remove key and test operation of remote. If this fails then a new remote plus coding to the car by your dealership is needed

You might try locking all the doors from the inside and then closing them all. Then try unlocking the car with the key itself (NOT THE FOB) manualy. Try a combination of these things, like maybe locking it manualy with the key itself too. Usualy some sort of locking or unlocking manualy with the key will reset the system. Its almost luike proving to the car that you are who you say you are.

I have an A4 and did this to re-program my key:

1. used the key to start the car...then turned it off
2. put the key in the driver door (door closed)
3. pressed the lock button on the key fob once
4. turned the key to lock the door.

This is basically the steps in the owners manual, but the car must be started with the key first, and the key must be in the door lock before pressing the lock button.
