I think my Cadillac Cimarron has the same issue. Good to know I'm not alone.

🔑 Car Key & Fob FAQ

Common questions about key programming, fob issues, and replacement options

Lost Keys
Yes, a skilled auto locksmith can extract the broken key and make a replacement. They can often do this without damaging the ignition cylinder. The new key will need programming if it has a transponder chip.
Key Tip: Replace key fob batteries every 1-2 years as preventative maintenance
Key Programming
Most transponder keys and smart keys can be reprogrammed if they haven't been damaged. Basic mechanical-only keys (no chip) can't be reprogrammed - they must be physically cut to match your locks.
Lost Keys
Dealerships can often cut keys using your VIN, but will require proof of ownership. This only works for original factory keys - aftermarket or previously replaced locks won't match. The key will still need programming to start the car if it has a transponder.
Key Programming
Professional key programming requires: diagnostic tools to access the immobilizer system, key code software, transponder programmers, and often proprietary manufacturer equipment. Some locksmiths and all dealers have these tools.
Key Fob Issues
1) Find the seam and pry open the fob (some have tiny screws) 2) Note battery orientation 3) Remove old battery (CR2032 is most common) 4) Insert new battery 5) Reassemble. Test all buttons - if issues remain, the fob may need reprogramming.
Key Fact: Smart keys use radio frequencies between 125 kHz and 2.4 GHz
