The battery in my VW key fob is dead, now I cant start the engine
The battery in my 2000 VW Golf remote key seems to be dead. I can manually open the doors however cannot start the engine or turn anything on once inside. I assume this is the immobiliser not being turned off. Other than changing the key fob battery, is there anything els I can do?

No. VW has made it nearly impossible to solve any key-related problems without a costly visit to the dealership. Battery must be replaced, and I assure you. the dealership will advise you that the ONLY place that you can find that particular battery is from the dealership. They like it that way.

General:open the door with the key.If no key availabile,learn how to pick a lock.If the lock is taped,there are several ways to brake into the car.Hint:less invasive,jack the car from under the engine try to open the hood or inject power into conectors.
you should still be able to use the keys to open the car. if you use a remote fob regularly then it is possible that the locks have seized up due to lack of use. spray the locks with a penetrating lubricant spray and leave them for a while before trying the keys again. you may have to do this quite a few times to free the locks. once free, the locks should be sprayed and opened and closed using the key at least every month to prevent them sticking again.
there is a way to get power to the car to use the remote fob on the central locking. using jump leads or a battery booster pack, you have to go underneath the car and connect the +ve (red) jump lead to the thick wire (10mm approx) coming from the started solenoid to the battery. do this BEFORE connecting the -ve (black) lead to a good earth point under the car. as the thick wire from the starter solenoid goes directly to the battery, the effect will be the same as connecting jump leads to the battery itself. this should give you enough power to operate the key fob and open the doors.
try this and contact us again if there are any further problems arising from the dead battery.
If im not mistaken,your car should have an alarm reset/override.Below the steering column,on the dash should be a slot where you put your remote transmitter to deactivate the alarm.If that works,you then need to have your remote checked and coded by a vw dealer.Good luck.
the remotes can be reprogrammed using vag-com. if you have power windows go to control module 46 , comfort module. then go to adaptation(10), then use the number 0 on the screen. press "do it". now you either go back into adapation or, whre you entered you 0, enter 1. it will ask how many keys you want to adpat, select up to eight keys. Then "do it", now you have upto 30 seconds to push a single button all all remotes you want to program. There should be a beep after every remote is programmed. If your don't have power windows, your first step instead of 46 will be 35, central locking.
No problem. The key fob is two pieces. The key part and the remote. Open the key as you would to sue it. Where the key flips open you can see a small recess about where the line of the trunck switch. This is where the key separates. You can pull it off or pry it with a small screwdriver. Once separated with remote part in your hand this also splits in 2. In the same area you split the key off insert the screwdriver in this recess and the fob will open giving you access to the battery. Also can be done by hand. It is a little tight so you will have to force which is normal. No screws just clipped. Make sure the battery is positioned in the right way and that you have 3 volts when you test the battery. 2.7 volts will make the remote not work or act funny.
