I’ve got a 2012 1993 Hyundai Sonata, would this method still work?

🔑 Car Key & Fob FAQ

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

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 Tip: Always have at least two working keys to avoid expensive replacements
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: Store your key code separately from your keys
Key Fob Issues
Many cars have a resync procedure: 1) Press lock/unlock buttons while near the car 2) Insert key and turn ignition on/off in a specific pattern 3) Use a sequence of button presses. Check your manual for exact steps - procedures vary widely by manufacturer.
Key Tip: Store your key code separately from your keys
