My '98 Shogun wouldn't unlock with the fob this morning, so I used the keys and set the alarm off. I tried a few times (probably to the annoyance of my neighbours) and changed the battery (indoors) to no avail. I then read this! I changed the battery beside the driver's door, pressed the big button twice and it worked! Thank you! One happy person :-)

when change the battery in the cobra remote control, you need to go near the driver side of your car then only you insert that new battery and you will then see the blinking in the LED...then press two times on the big button.Done

Thanks for the tip about holding the 2 buttons. My car has been without an alarm for weeks after changing the batteries.

Much appreciated

Do you have the remote with two grey buttons or has it got one yellow and one green?

If the first with two grey buttons then this is probably what you need to do.
Assuming the remote appears to work, ie the light comes on.

Press and hold both buttons together, the light will flash as you do this, wait till the light goes off (about 10sec) let go of the buttons and the light will come back on, press the larger of the two buttons, the light will flash then go off, press the same button again and it should arm/disarm.
If its the other type with the green and yellow buttons it may be a build up of carbon on the PCB, open it up and clean where the button makes contact with something that wont damage the circuit, or possibly need reprogramming.
