Customer Question

I have just bought a 2003 hyundai coupe 2.7 v6. I decided to change the batteries in both key fobs only to find they both now don't work! Obviously I can get in to the car and set the alarm off. Can you tell me from then how I can 1. Shut the alarm off and 2. Reprogram the fobs?!

If you change the batterys in the FOB was changed then do just the following .

These instructions only work if the remote you are programming has already been programmed to your vehicle.

For example if your battery went dead on the remote or
it just became unprogrammed for some reason.

These instructions WILL NOT programm a new remote to you car.

To program a new
remote to your car a dealership or locksmith must hook a computer up to your car.

1. Get in car, close doors, turn key to ACC.

2. Hold open button down on remote, until blinkers flash.

Now do the same with the second remote .

Now the remotes should be working if the blinkers do not flash you will have to see your dealer for programming .
