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 Tip: Store your key code separately from your keys

Key Tip: Always have at least two working keys to avoid expensive replacements
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
