cobra car alarm how to reset

i had my battery out my car for a day now my key fob wont work it ,its a cobra 7905 one and i cant find the instruction can anyone help.

I believe hold down the larger button for ages...3 mins or so?

Reset my old Cobra 5 series so might be worth a try?

If it's like the Cobra I used to own, you hook up the battery and within 30 sec., push and hold the "arm" button. There should be a confim chirp after a few seconds to let you know it's reprogrammed. If you have more than one remote, I think they have to be done less than 1 minute apart...

Hope that helps.

put a search in google, i had the same prob with mine.
There is some pages that show the original instructions, its easy to rectify
