Trying this on my 1985 Porsche 911 later. Will report back.

My 1985 Porsche 911 has the same problem—any luck getting the key code?

My 1985 Porsche 911's been in the garage for a week over this. Thanks!

This just might solve my 1985 Porsche 911's ignition issue.

🔑 Car Key & Fob FAQ

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

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 Tip: Consider key insurance for expensive smart 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: Always have at least two working keys to avoid expensive replacements
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: Consider key insurance for expensive smart keys
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.
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 Fact: Many cars can store up to 8 different key codes in memory
