Fuel door lock fix?

The arm on the fuel door lock that rotates and engages to lock the door is gone. I can replace the whole lock, but would prefer to keep the original since the key matches the door keys. Are there any tricks or tips to replace just the arm? I don’t actually care if the door locks, just don’t want it flapping in the breeze... any suggestions?

 

Just change the door to a regular door, mine has no lock and it doesnt flap.

 

On my old 4Runner, the lock cylinder and arm were retained to the fuel door by a sliding clip on the backside.

If you learn there is no way to replace the arm itself, try taking the original lock and a donor lock to a locksmith. A locksmith can probably swap the original cylinder to the donor lock easily.

 

I don’t see a fuel door without a key on the Toyota parts diagrams. You’re talking 1st gen, right? Any idea on part no?

 

Thanks. Yeah, that was plan B, or just live with a 3rd key.
