I picked up this 07 XKR in Oct. last year with 19,000 miles. I replaced the key fob battery at that time just because. One month later the key fob battery warning comes up so I replace it again. One month later warning again so I replace again. That one lasted until couple weeks ago so I put the first new one back in and it lasted a week and again a warning. Car is located about 30' from where fob is kept when not in use, locked, with tender plugged in. What kind of life are you experiencing with these fob battery's?

 

I've had my 2007 XK since September 2013 and it's still on the same fob batteries. Never had to use docking.

Sounds like the fob may be faulty; I've had mine for 2 years and have not had to replace the fob battery.

 

I change my battery every 2 years. I use the remote function for opening and closing the rooftop a lot. My guess is like Ngara's, a faulty key fob. The same problem with your spare one?

 

Yeah, I can only imagine the cost of a new key fob? Anyone know and what the process is for pairing(?). If this is what it's called....

 

New fobs need to be configured using the Jag diagnostic system, so you need a dealer or indy specialist. Be warned - I believe that, if a fob has been paired to one car, it has to be un-paired before it can be paired with another. So beware of buying used fobs unless they come with a guarantee that they are no longer paired to any car.

 

Probably somewhere between $300 to $400 for the fob and programming. Just buy a new one. It will save you headaches.


Wish Jag had saved the money on the keyless system and spent it on decent sat nav and a coolant temp gauge...

 

You can buy key fobs on Ebay. As I recall there is a wide price range, say from $35 -$165. But, as Ngarara says above make sure that what you buy is "unprogrammed". Here's the link:

Good luck.

 

This thread reminds me of days gone by when all we had were keys! How times have changed!

Quick key story....

My Dad had a 1984 Mercedes SL (Dad's gone now but Mom still has it parked in the garage). Anyway - soon after they bought it they went to a dinner party at a house some distance away. Turns out the evening was warm so Mom left her coat draped on the seat and they went to the party. As they started the drive home - Mom realized her coat was gone...

Dad stopped the car to have a good look around and as he got out to walk over to her side he realized..... This wasn't there car. Not even the same color.

They drove it back to the party. Put it back at the curb.... and returned home (with Mom's coat) in there SL.

Fobs are a pain some times but keys certainly weren't perfect....even on a Mercedes!
