If the fob hasn't been used in a long time, and another one was being used, the keyless entry system simply needs to be programmed to 'see' the fob's codes again. The instructions for this are usually in the owner's manual. If you don't have an owner's manual, try calling a dealership and asking; sometimes you're lucky and can get a nice person who doesn't mind helping someone out. Good luck! :)
your batteries have run out of power
You need to change the batteries or charge it with a charger that you can get at game stop
if your using a remote try changing the batteries
replace the batteries
i put new batteries in remote and just the hatch works door maks a click
two things replace the 2 batteries inside the key ( IT'S THE ONE THAT LOOKS LIKE A QUARTER ) you are out of range
First thing to do is replace the batteries in the remote. If that doesn't work, try a replacement remote control if you can but if these don't work, it might be time to talk to a repair technician.
possible weak batteries?
If the engine turns over the batteries are fine. Diesels require special equipment to troubleshoot, take it to a shop that is competent in diesel engines.
the battery might be in upside down,i know as i now own a focus myself,and put batterys in wrong way.
if they are rechargeble batteries then yes you can but they wont stay charged for that long
y to sync your remote with the wii. To do this, open the wii remote so you can see the batteriesand next to the batteries you'll see a red little button, then get to your wii, open u the little flap on front of the wii and you'll see another red button. press the button on the wii and the remote on the same time, the wiimote flashes light and should then connect to your wii. note: your wii must be turned on and your wiimote batteries should be full.
