My Rieju Mius just sits silent—hoping this changes that.

🔑 Car Key & Fob FAQ

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

Lost Keys
Locksmiths or dealers can: 1) Decode your door or ignition lock to determine key cuts 2) Access your car's key code through manufacturer databases (with proof of ownership) 3) Program new transponder keys using diagnostic equipment.
Key Tip: Keep spare keys in a faraday bag to prevent signal amplification theft
Security Systems
Some systems reset by: 1) Disconnecting battery for 15+ minutes 2) Using original keys in specific sequences 3) Professional diagnostic reset. Consult your manual - procedures vary. Persistent issues may require dealer-level tools.
Key Tip: Replace key fob batteries every 1-2 years as preventative maintenance
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: Store your key code separately from your keys
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 Programming
Professional key programming requires: diagnostic tools to access the immobilizer system, key code software, transponder programmers, and often proprietary manufacturer equipment. Some locksmiths and all dealers have these tools.
Key Fact: Key programming typically takes 15-30 minutes for professionals
