Remote not working X Type Sport

my remote battery is good, even put in a new one, both register about 3.3 volts…any ideas friends…?? Art.

The circuitry and buttons can wear out and break over time. I had to recently replace the electronic part of the key fobs for my car. My Jag mechanic got the replacements from an after-market supplier in China, at a greatly reduced price over Jaguar. They look the same and snap into the key part perfectly.
