Does anyone know if this works on push-start BMW F800Ss?

🔑 Car Key & Fob FAQ

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

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 Fob Issues
Common causes: dead battery (most common), water damage, internal circuit damage, or the fob lost synchronization with your car. Try replacing the battery first. If that doesn't help, the fob may need reprogramming or replacement.
Cost & Options
Some comprehensive auto policies cover key replacement, often with a deductible. Homeowner's insurance may cover keys lost away from home. Always check your policy details - coverage varies widely. Claims may increase your rates.
Key Tip: Keep spare keys in a faraday bag to prevent signal amplification theft
Key Programming
Most transponder keys and smart keys can be reprogrammed if they haven't been damaged. Basic mechanical-only keys (no chip) can't be reprogrammed - they must be physically cut to match your locks.
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 Fact: The average driver will lose 1-2 car keys during ownership
