Steps:
the battery might be in upside down,i know as i now own a focus myself,and put batterys in wrong way.
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
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.
does the kia have a remote voltage regulator
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
clutch & pressure plate were replaced remote was changed engine turns good but car wont fire, power reaches coil but does not reach plug leads coil was replaced new same issue car wont start, remote seem to be working good! unlock with key engine does not turn use remote engine turns good! can you help please?
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.
if they are rechargeble batteries then yes you can but they wont stay charged for that long
