key fob not working

Hello, I own a 2009 Jaguar XKR Convertible.My problem is thekey fobwill not open (lock or unlock) the car...the fob worked yesterday and past years.I changed the battery (#2032) and it still doesn't work. I operated the key fob all around the car and even the fabric top with no luck. Since the car battery might be low (5+years old), I'm putting a trickle charge for 48 hours to make sure it is charged before I manually use the emergency key to open the door and hope I can turn off the alarm.
No work has been done on the car except oil change, brakes etc. a few months ago. Some people said it might be a faulty BCM and maybe have a diagnostic check (and if so, the fobs are probably not connecting to the car) and ask if it can reprogram the existing BCM module (if corrupted reprogram with SDD?) and the key fob as well.
Others said to disconnect the negative battery terminal for 5"ormaybe a "hard dump"? to disconnect both + and - leads for 15 min. and hold both together to clear fault codes??
Someone looked at the wiring diagram, and said there are 2 fuses that should be checked. Fuse F3 20A which supplies the Keyless Vehicle Module and fuse F19 5A which supplies the RF receiver, both are located in the central junction box in the front passenger footwell...fuse 29?
Does anyone know of a Jaguar independent engineer or a Jaguarspecialist in the western suburbs of Chicago?
Help...any advice would be appreciated. Thank you.

Welcome to the forums Ron,
Take a pause and do some forum reading BEFORE EVEN CONSIDERING reprogramming the BCM or any other module. If the Smartkey worked yesterday and nothing else has changed, modules are extremely unlikely to have failed overnight and you could easily dig yourself into a very deep and expensive hole. I've copied your post to X150 forum for advice from other members with the same model. Here's the direct link to it:

I can see you've already found your way to the main XK/XKR forum as you posted there in 2017 so there's no need for a link to it from me. The 'HOW TO' thread at the top is a good place to start for information on regular issues. You can also use the US Midwest Region forum by following this link https://www.jaguarforums.com/forum/us-midwest-39/ to find other members in your region.
Please read the guidance for new members ( https://www.jaguarforums.com/forum/n...ned-up-241802/ ) which answers many of the most frequent questions about getting started.
Enjoy the forums.
