Remote Key Not Working After Battery Change

[clumpymold]

I know this is an old thread but I just replaced the battery in a key and was having this same issue. Here is the combo that worked for me:

Car is already unlocked...
open door
get in
insert key (that has new battery)
turn key to accessory position (don't start the car)
now push in unlock button on the key remote
hold button in 10 seconds
let button out
press button in and out 10 times
turn key off and remove it
get out
enjoy your working remote

I actually replaced both key batteries at the same time and this same procedure worked for both.

Nice. Just followed this with my spare key and it worked perfectly! :)

I didn't change my battery but the battery died due to leaving my lights on and I jumpstarted it, ever since my remote would not work, I tried every single method on this thread and it wouldnt work.
I tried one method that worked at first (but then after testing the remote function more than twice it stopped working). Can anyone else give me a suggestion, this is becoming very frustrating!

How do I reprogram the remote control?

1. Take the valet key, put it into the ignition and turn the key to the "on" position, just prior to starting the car.

2. Roll down the driver's side window (not required, but a good idea in case there's a problem).

3. Exit the car and close the door.

4. With a second key, physically lock the doors (don't use a remote).

5. Take the first remote to be programmed, press one of the buttons and the lights will flash once. Wait 10 seconds and press the unlock button. The doors should unlock. That first transmitter is now programmed.

Have you tried what I did (see post #31)?

And why would leaving your lights on kill your battery? Don't our lights turn off automatically after a while?

Yup tried post 31 and it didnt work, the method I posted last might have actually worked this time im not sure if it'll last...I also thoughts the lights turn off automatically after a while but apparently not. I took it to valet and when he brought my car back to me he switched the headlights from the "auto" setting to the setting where you force them to turn on, and I didnt realize that. When I parked my car at home the next morning the car was completely dead, so I figure it had to be because of the headlights staying on all night...but maybe I'm wrong and it was a freak coincidence?

Weird just went to test the remote again after it seemed to be working directly after I tried the valet key method, and now it doesnt work again...it's a mystery i guess ill have to go to the dealer and suck it up

Wow, that sucks. Glad to know that. I always thought the headlights would turn off after a certain time. I never have mine on Auto anymore anyway. My damn Ziza city lights throw a code if they're turned on automatically. Hope you figure our your remote issue though.

Hey, wanted to say thanks. Thought you might be a joker at first, i.e. in the lines of jump up 3 times, turn around, close your eyes and snap your fingers 25 times and it will work...I promise. All good with spare key. Tanks!

In case someone else finds this; this worked when my 2008 Fob stopped working

Steps to reprogram keys to a car they are already linked to:
1. Press and hold the unlock key on a remote
2. Insert key in ignition and turn to on (while still holding unlock)
3. Hold unlock while in the on position for 2 seconds
4. Turn key to off, remove from ignition and release button.
