Has anyone found or installed an aftermarket lock on the fuel door. Twice I have come out of a Hotel in texas where the door was open. I suspect someone checked to see if it was really a diesel, but this concerns me.

Thanks for ideas....

I looked into the aftermarket and found nothing, unless you want to modify (drill hole for lock, no direct replacement) your fuel door yourself for a lock. I had an old '04Jeep Wrangler locking gas cap off a Rubicon I had for 13.5yrs. and it fit, so problem solved for me. Mac

Locking cap maybe best option. Be nice if the fuel door had to be opened from inside the cab but oh well

Yes a locking fuel door is really a must.
We have had kids slashing tires and smashing windshields around here.
Think of the cost if they dumped some dirt in the fuel filler or def filler all because the fuel door doesn’t lock.

I bought a diesel Locking gas cap from dietz. So far so good. Locks keep honest people out, if someone wants to break it, they will.

Do you have the part number for the cap you have? All I've been able to find is a relatively pricey but neat aluminum model that only comes with one key.

I like the look of that green one, but would want a def cap too, and it looks like they don't make one for the Colorado yet. Plus, that would be just another key to carry around.....
