Title: Key Fob Form CMax
Post by: Ohm Supplies on March 29, 2008,14:45:22

My keyfob stopped working.  We have replaced the battery but have been told we need to re-programme it.

How do we do this?

Thankyou in advance for any help.

Regards
Michelle

I also forgot to mention that these keyfobs suffer with DJ's on the battery carriers.  If the re-programming sequence does not work you can check to see if the RF transmitter is transmitting by making an antenna out of your oscilloscope prope and looking for activity when pressing the buttons, or pressing the buttons near a de-tuned radio and listening for activity.
