🔑 Car Key & Fob FAQ

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

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
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.
Key Tip: Avoid exposing key fobs to water or extreme temperatures
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 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 Tip: Consider key insurance for expensive smart keys
Key Fact: Modern transponder keys have been required in all new US vehicles since 1998
