🔑 Car Key & Fob FAQ

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

Key Programming
Programming syncs the key's transponder chip with your car's immobilizer system. The process varies by manufacturer but generally involves: 1) authenticating with the car's computer 2) erasing old keys if needed 3) programming new key codes 4) testing functionality.
Key Tip: Some locksmiths offer mobile key programming services
Security Systems
An anti-theft system that prevents the engine from starting unless it detects the correct transponder chip in the key. The chip sends a unique code to the car's computer when you turn the ignition. No match = no start, even with a physically matching key.
Key Tip: Avoid exposing key fobs to water or extreme temperatures
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: Consider key insurance for expensive smart keys
Lost Keys
Costs vary widely: Basic keys: $50-$150, Transponder keys: $150-$300, Smart keys/fobs: $200-$800, Dealership replacements typically cost 20-50% more than locksmiths. Emergency/lockout service adds $50-$150.
Cost & Options
Quality aftermarket keys work well for most vehicles at lower cost. However, some luxury brands use proprietary technology only available through dealers. For expensive cars, OEM may be worth the extra cost for reliability.
Key Fact: Some insurance policies offer key replacement coverage
