i recently bought a car with a Clifford g4 alarm...well from checking the pictures on ebay, that's what the fob matches to, i need to obtain a pictured type user guide so i can change the twerp settings for entry to the vehicle and to fully understand the system itself with the valet buttons. The pictures on the fob have rubbed off with use!. I also think the battery's are close to dying so i don't want to get caught out..any help would be appreciated
