🔑 Car Key & Fob FAQ

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

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 Tip: Newer cars often require dealer programming for first key replacement
Key Fob Issues
Common causes: dead battery (most common), water damage, internal circuit damage, or the fob lost synchronization with your car. Try replacing the battery first. If that doesn't help, the fob may need reprogramming or replacement.

Key Tip: Some locksmiths offer mobile key programming services
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 Tip: Replace key fob batteries every 1-2 years as preventative maintenance
Key Fact: Some luxury car keys can cost $800+ to replace at dealerships
