🔑 Car Key & Fob FAQ

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

Key Fob Issues
Sometimes. Broken buttons can often be fixed by cleaning or replacing the button pad. Cracked cases can be glued. However, water damage or circuit board issues usually require complete fob replacement. Reprogramming is still needed for replacement fobs.
Cost & Options
Locksmiths are typically 30-50% cheaper than dealerships for key replacement and programming. However, some newer models (especially luxury brands) may require dealer-only programming tools. Always get quotes from both.
Key Programming
Common reasons: wrong key type for your vehicle, anti-theft system needs reset, low car battery voltage during programming, or the key isn't properly synced. Some cars also have programming limits (only 2-4 keys can be registered).
Key Fob Issues
Sometimes. Broken buttons can often be fixed by cleaning or replacing the button pad. Cracked cases can be glued. However, water damage or circuit board issues usually require complete fob replacement. Reprogramming is still needed for replacement fobs.
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 Fact: Key programming typically takes 15-30 minutes for professionals
