SOURCE: key fob will not undo

If you don't have one that works for the vehicle now, you'll have to take it to your local dealer to have it programmed to the vehicle. Some will charge for this, some will do it at no charge.

If you do have a remote that is programmed and working for the vehicle, then the following steps will allow you to program another remote:

1. Enter vehicle and close all doors.

2. Put seatbelt on (or clip it into the buckle) to shut the warning buzzer off.

3. Put key in ignition, turn to run position but don't start it.

4. Press and hold the unlock button on the working key fob and hold for 4 seconds, then also press the panic button.

5. Release both buttons and you should hear a single chime to indicate it is in program mode. You have 30 seconds after the chime to program any additional remotes you want to program.

6. Press and release both the unlock and lock buttons simultaneously on the remote you are programming. You should hear another single chime.

7. Within 4 seconds after hearing the chime, press either lock or unlock button on remote that you are programming.

SOURCE: key fob not working after changng battery

Bring it to a "Batteries Plus" type store; they can repair the fob if it is ony a broken battery clip. They did it for me for free! IF it is not the fob, then bring it to a dealer??

How do you syncronize the ford courier key with the car for central locking


Hello Madonna Goulding

I'd would need to have the year of your FORD to be
sure on telling you how to proceed... but a battery change
should not affect the existing coding.

It sounds as though you are mixing your question about
KEYLESS entry (FOB)... and your
PASSIVE ANTI-THEFT SYSTEM (PATS) KEYS.

For security purposes...
BOTH of your original keys must be present...

You can... and SHOULD have more than two keys
but you can NOT have LESS THAN two keys to
do any PROGRAMMING, ADDITIONS or modifications.

(FOBS or KEYs)...
YES... YOU DO HAVE A "FOB"... but yours is added to your KEY-TOP... treat it the same (I believe your manual refers to it as a keyless "REMOTE"
(attached key notwithstanding).

THIS is the design INTENT... to prevent
valets, garages... or ANY UNAUTHORIZED person from
creating UNAUTHORIZED SPARE KEYS.

The cloning process is in your OWNES MANUAL.

If you do not have TWO KEYS you MUST go to a
LOCKSMITH or a DEALERSHIP to REGAIN your TWO KEY
functionality...

Used my Valet key last night and now my Audi A4 wont start, is this related to using the valet key?


more than likely as the fob key has a chip that syncs with the security system etc , have you got the owners handbook as this should give you the procedure that needs to be carried out to reset the fob key,can't take the credit for this fix as found it at an audi forum give it a try .
I learned a new trick tonightbiggrin.gif. I recently changed the battery in my key and it would no longer open the door locks. I just sat down and read the manual and found that if you replace the battery you need to re-synch the key.

Here is how it's done.

replace the battery. ( pry open the little tab at the seam in the key, then split the bottom in two with your finger)

Press the lock or unlock button once.
with-in one minute put the key into the drivers door and lock and unlock it manualy.

TADA it works again biggrin.gifbiggrin.gifbiggrin.gif

I have seen a few threads and questions that said there fob stopped working. so I thought I would throw this out there. I hope that some of you with this problem that don't have manuals because the previous owner kept it for a souvenir will find this Helpful.

2003 audi a4 door wont unlock with or without key after changing battery in key fob


Your KEY will not unlock the Door? That has nothing to do with the FOB.

OR do you mean your FOB will not work at all?. If it is a PROGRAMMING ISSUE, you need to contact your Dealer

I cannot lock or unlock my car with my key fob


Test the battery inside key fob, should be at 3 volts, if is less than 3 volts replace the battery. If that does not work you may need to replace the key fob, on this vehicle you can program the key fob through the radio, the car manual shows you how to do this.

Before replacing the old key fob you can try to resinc the fob to the car by pressing the lock and unlock buttons at the same time for about 15 sec, if the door locks cycle the the fob will work again.

1999 porsche 996 replaced key fob battery disconnected battery now trunk releses are locked and cant access battery.How do you open frt trunk manually


Assuming the car battery is ok (if not, buy a male to male cigarette lighter at the auto store and connect to another car until charged enough to unlock the doors...but don't try to crank the ignition!). The trunks won't open if the battery went dead with the alarm set because arming the alarm physically locks the releases.

Sounds like the key code is switched off because you replaced the key fob battery. Try unlocking the car manual with the key in the door lock. Then switch the ignition on to reactive the keyless entry. If this does not work, you might also try pressing the fob unlock button with the key in the door lock until the dash led flashes.
