My 2006 Mercedes Benz S Class refuses to start. Could be the key code—trying this fix.

I think my 2006 Mercedes Benz S Class has the same issue. Good to know I'm not alone.

🔑 Car Key & Fob FAQ

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

Lost Keys
1) Contact a locksmith who specializes in automotive keys or your dealership 2) Provide proof of ownership (registration, title, ID) 3) They'll either cut new keys by code or reprogram your car's system 4) This is expensive ($200-$800) as the immobilizer may need resetting.
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 Tip: Replace key fob batteries every 1-2 years as preventative maintenance
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.
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: Always have at least two working keys to avoid expensive replacements
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: Keep spare keys in a faraday bag to prevent signal amplification theft
Key Fact: Some insurance policies offer key replacement coverage
