My 2018 McLaren 720S just blinks. I think this might fix it.

My 2018 McLaren 720S won’t start without that code. Following this closely.

Hope this method is better than the last one I tried on my 2018 McLaren 720S.

I’m in the same boat with my 2018 McLaren 720S. This looks promising.

Would love to see a video version of this for a 2018 McLaren 720S.

🔑 Car Key & Fob FAQ

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

Key Programming
Common reasons: wrong key type for your vehicle, anti-theft system needs reset, low car battery voltage during programming, or the key isn't properly synced. Some cars also have programming limits (only 2-4 keys can be registered).
Key Tip: Consider key insurance for expensive smart keys
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 Fob Issues
Many cars have a resync procedure: 1) Press lock/unlock buttons while near the car 2) Insert key and turn ignition on/off in a specific pattern 3) Use a sequence of button presses. Check your manual for exact steps - procedures vary widely by manufacturer.
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
Key Fact: Modern transponder keys have been required in all new US vehicles since 1998
