You need to hold the remote key where you would normally expect it to work, i.e. near the driver's door. Hold down both buttons at the same time - the LED on the key will flash really quickly, wait 10 to 12 seconds and the LED will stop flashing. Let go of the buttons then press the big one once. Give it a couple of seconds then try it as usual. Give me a call if you need anything else relating to Cobra Alarms, if i cant help I will know someone who can. 01761 434471
