Saved me from towing my 1991 Porsche 944. Thanks!

Just what I needed! My 1991 Porsche 944 has been acting up lately.

Was about to give up on my 1991 Porsche 944, but this gives me hope.

This forum is more helpful than my dealer. Thanks from a 1991 Porsche 944 owner.

🔑 Car Key & Fob FAQ

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

Cost & Options
1) Always have at least 2 working keys 2) Get spares made before losing originals 3) Consider key insurance/add-on coverage 4) Store key codes safely 5) Use protective cases for smart keys 6) Program new keys before old ones fail completely.
Key Tip: Keep spare keys in a faraday bag to prevent signal amplification theft
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 Fob Issues
1) Find the seam and pry open the fob (some have tiny screws) 2) Note battery orientation 3) Remove old battery (CR2032 is most common) 4) Insert new battery 5) Reassemble. Test all buttons - if issues remain, the fob may need reprogramming.
Key Tip: Some locksmiths offer mobile key programming services
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.
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 Fact: The average driver will lose 1-2 car keys during ownership
