My keyless entry stopped working, how do I fix it?

well a quick way to reboot your car is try this Only if you have the Stereo Codes*. Unhook your battery and leave the car for about 15 -20 minutes. Reconnect the battery and put your key in the ignition turn the key to power on for 10 minutes leaving it in the power on position *do not crank the car over* after that turn the key back start the car shut it off. Get out and try your key if this does not work let me know. And you only need to do the second part if your car has an immobilizer equipped. You can tell by a key symbol on your dash when you flip the ignition to power on.
