Hi Andy, i agree, but we manufacture transmitters and receivers, and we do have a PIC based solution, but we are trying to incorporate the receiver software into our control card for the motors, and that one is 51 based. Any way as you know the Keeloq system requires a manufacturers key, so there is no point in trying to pick that. We genuinely need a 51 solution. Please look at our web site at www.ecp.pt
Thank you and i hope to hera from you again
Jose
