Once all of the fobs have been programmed, repeat the process once again. Put your key in the ignition and start the automobile without running the engine. Then, using your first key fob, press the lock button. At this point, you should be able to hear your car’s locks unlocking to confirm your success.

All of your key fobs should be programmed this way to ensure that they all work. Each key fob’s lock sounds when you have successfully opened it, so you know you’ve done it.

Practice makes perfect, so don’t be too hard on yourself when your car key reprogramming doesn’t work out the way you expected.
