try the other fob.
the buttons on fobs can short.(its just a plastic membrane with carbon pad in the fob and can go bad.(cracks or crumbles inside...........)
so put the suspected fob far away from car, and use the good new fob. work now, and a new FOB battery, too.
if you only have one fob, now's the time to get the spare.
no fob lasts forever. not not ever.
I just changed the battery in my fob for 2011 Journey Crew, with the battery removed ( from fob ) I did start my car by pushing the start button whith my fob... so the theory is tested and true.... also the battery you'll need is CR2032 available everywhere... and removing the battery will NOT remove the programming of your fob ( also tested )... so no need to visit the "steelership" Hope this helps....
unlock the car with the key and hold the key over for 30 secs,(the windows will go down) then lock the car/hold key over for 30 secs,(the windows will go up). wait 30 secs then press/hold down the unlock button on the key fob,this will resyncronise the alarm/key fobs.
Im not sure there is any easy fix for this so I will just give a little advice.
Can you give me the make and model of the car? and is the alarm and immobilizer a standard factory one? Will do my best to help you once I know the make and model, and the year please.
The battery in your remote key fob can be changed.But the spare key has to be programed to work.Take your main key to the dealers And have them do it for you.
You probably caused a short circuit when you changed the light. Change fuse #14. Next time, don't turn the lights on until you are finished changing the lights.
get in your car close door hit the unlock button then put key in the ignition cycle the key from off to on (STOP BEFORE START POSITION) cycle key off to on 7 times after the 7th trime the doors should lock the unlock automatically that means u are in trainning mode hit the unlock button on key fob. the key fob should now work if it doesn't then try changing batt
