Are you trying to unlock them with the key or the remote?...If they don't work with the key....check the fuses for the pneumatic pump to make sure it is working....Jim

Thanks Jim.
Remote control battries were weak but I did not know how to open the case of the remote control. So I decided to look into the owner's manual and all the instructions were there. Replaced the batteries and it works great. But thanks for providing me another place to look if batteries did not work.
