How to change battery in jaguar xf key fob? - 2007 Jeep Grand Cherokee Overland

When changing batterys to fobs some times you have to reprogramme them to the car , go on youtube and ask the same question as a few cars need to reset different ways

try a battery reset.ie. disconnect battery neg terminal and leave 10mins reconnect and retry lock and unlock then see if the smart key is regonized if not check the smart key battery specialy the contacts it may be the key is not been reconized but if it cranks but not start may be a engine management system or fuel delivery problem if it has asked to insert smart key the key battery is poss flat.

My Genesis has the battery in the trunk and the owners manual shows using the key hidden in the FOB and using the keyhole under the trunk lid. Why does your key "blade" not work?

only by by using jag diagnostic tool. if its a previously good fob that worked on your car the battery/ holder could be the problem.if its a replacement the car has to be programmed to accept it.

Maybe your keyfob needs a new battery as well

you may have the battery in backwards
