1996 discovery central locking woes!

Hi guys hope someone can help me.

My central locking is playing up. key fob had the battery replaced since then it wont work correctly. The fob is a 2 button type. I have to open the car with the key then the alarm goes off. This will reset after an age of pushing the fob buttons. Its getting to be a right royal pain in the ass! I have searched the threads on here and there seems to be a number of different resets available. So my question is do i push the fob locking button 3 times or 4? Do i put the key in the lock and lock it 4 times? Do i hold the lock button on the fob and try to lock and open? Please help thanks. Chris.

"do i push the fob locking button 3 times or 4?" Look in your owners hand book, it states 4 times the first three nothing happens and on the fourth the doors lock.

Also fobs have been known to loose their tuning and therefore require a repair which companies like Remotekey can do for you.
