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: hi,immobiliser problem?battery went flat,,managed to

Hi it sounds like you have done everything you can do, it now looks like your going to need to get the immobilizer reset, this can be done at most garages but its best if you shop around to see the best price you can get as its not cheap.

have you tried locking the door with the key and then opening it with the key then try the car see if it will work.

failing that its going to need the imob re-programming so that it accepts your key fob, it may just be that you need the fob replacing as the chip inside could have failed they will be able to test all this for you.

let me know if you need further assistance, not that theirs much more i can do without being their with the equipment to test the immobilizer, hopefully it will just be the fob that needs replacing.

you could just try one last thing when you get in the car and put the key in the ignition try holding the fob as close as you can to the ignition barrel as this is where it picks the signal up from so try holding it close to their and see if that then lets you start the car

failing that its going to be a trip to the garage.

plz rate this solution as i have a whole page of unrated posts, thanks

What's a 99.5 Jetta?

Anyway, there should be a button battery located in the key fob. Swap that out and you may be able to use it like normal. Another option is for your to try disconnecting the battery. There is a chance this will reset your alarm and you can use your car as normal. Or the alarm will just go off. These things are finicky.

I don't see where you have any choice but to unlock the doors with your key. If your fobs have good batteries, then the problem is with the alarm system, which can't be accessed until you unlock the doors. I'm not sure what the procedure is on your particular alarm, but with most alarms, you disarm the system by first turning the key in the door lock to the left and then to the right to unlock the door. Turning the key to the left first, disarms the system. Some aftermarket alarms will have a button hidden under the driver side dash that will disarm the alarm.

Find the alarm and disconnect it, or locate the fuse to the alarm and remove it. Then you can charge the battery without all the noise. Once the battery is charged, hook the alarm up and disarm it with the remote.

Alarm problems


You probably need to replace the battery in the key fob. Even if the fob has a little red light that comes on, the battery could be low enough to not disarm your alarm. That little red light only needs a minimal amount of battery power to light up. Try a Radio Shack store and they will most likely hand you a screwdriver to pry off the back or remove the screw. Once it is open they should have the battery you need. Should be about 6 bucks +/- depending on your location.

Won't start after cleaning battery terminals


Sounds like you have an aftermarket alarm with starter disable. By disconnecting the battery the alarm reset and the defualt setting is usually to set the alarm automatically (active arming). You have three options..
A. If you have the key fob that went with the alarm you can disarm the alarm.
B. If no key fob is available you can disconnect the battery again, turn the ignition key to the on position and reconnect the battery. This usually doesn't allow the alarm to set and allows the car to start.
C. Remove the aftermarket alarm system. This is usually the long term fix i recommend if the fob isn't available. Option B should get you going though.

Key fob wont disable alarm on hyundai coupe


One day my Hyundai Coupe 2002 2.0 car alarm would not dis-arm. The remote was flashing but not turning the alarm off. I replaced the batteries and had the remote signal tested, but still the alarm would not dis-arm. There are no switches to flick off, no reset button and there was no way off cutting power to the alarm. The only solution was to take it to a Hyundai dealer ( with alarm siren sounding and lights flashing ) and have them disarm it. It took one guy almost 3 hours to disarm it, and cost me £150 ! I knew the guy at the garage, so that was with discount. The alarm is a joke and should not have been fitted in the first place by Hyundai!
