You may have a problem with your PEM. A number of PEMs were shipped that have faulty transistors on the PCB. Most of the time it will work fine, except when the PEM gets hot, like on a Hot day. Then you will get the "key not detected" or "damaged key" error. This can be fixed with a flash to the PEM.
