Can someone direct me to, or provide instructions for opening the X300 1995 XJR remote fob so I can see the FCC transmitter ID?

I need to examine the last 3 numbers of the FCC transmitter ID to determine the frequency of the fob. I have one fob that works fine and a another one I bought on eBay that doesn't. I want to rule out frequency mis-match before I go any further.

I just don't want to do anything wrong to damage the fob while opening it since these things are so rare (and expensive).

Thanks!!

 

If it is the same as the fob for a 1995 XJ6 with the 2 buttons it is just a case of using a sharp tool to pry open one end of the brass ring and then pulling the ring away from the fob. Then use a knife to pry apart the 2 halves.
That's how I did mine.

 

is there a battery in there ??

 

The freq . is on the the outside of the battery cover itself and it takes 2 X 3 volt batteries . You need good light or a magnify glass in the dollar isle at the hardware store or you can test drive there more expensive magnifying glass product offerings . Be careful of the cheap dollar store batteries .

Don't pry on the battery cover as the removal instructions are in TSB 18- 9 below and replacement microswitches and rubber button covers are avail on Ebay , cheap and free shipping . There are a couple of TSBs on the FOB in this source starting with 18 - 4 :

1995 is most likely a 315 hz and 433 hz came in later on the X300

Just picked up a 315 from a small salvage yard for $ 20 and will see if it works later .
