Iím not sure about the quality, as Iíve never bought a locking gas cap before. I do wish it was tethered to the side so that I wasnít worried Iíd leave it at the gas station. But it serves itís purpose.
ProsTwo sets of keys.
ConsNot tethered.
By Cat
Not for me
July 22, 2019
The lock on this gap is tricky to work and it seems a bit cheaply made. No tether on the cap and nowhere to rest it easily. Opted to return it. Planning to get the model that you need to have keyed.
By Trevor
Just what the doctor ordered.

Fits perfectly and solved the problem I had with the check engine light. Also keeps the gas tank secure, of course.

This gas cap is light weight and the locking mechanism feels a little flimsy but if you're easy with it it'll work fine. Seals perfectly. I agree, a tether would be nice. This cap accomplished my goal and the price was right. If you need a lock, this will do it.

Works as designed!

Put this on our new '19 JLR. No issues whatsoever. Gives me a little more peace of mind. Would definitely buy again.
ProsEasy to install Peace of mind Good value for the money
ConsYou have to remember to hold the cap when you're locking/unlocking it with the key, or it just spins. Not really a con, but I always forget until I try to lock or unlock it.

PITA to unlock
March 27, 2019
It works however takes 5 minutes of messing with it to get the the key in to get it unlocked. It now sits on my workbench. Waste of money..

Exactly what i needed
February 25, 2019
I recently bought a 2006 jeep liberty and the check engine light kept coming on. I realized there was an aftermarket gas cap on it that didn't have the correct seal. Purchased this gas cap and everything is back to normal. Easy to use.

Safe & Secure
October 23, 2014
I purchased this product to protect my Jeep Liberty while it sits outside unattended at night. I do not understand why many manufacturers don't bother securing the vehicle's fuel supply with a remote door release feature--simple and relatively inexpensive. Now, I can be confident that no one can steal my Jeep's fuel or ruin it by adding something destructive down the fuel filler tube.
ProsSimple and easy to use, fits well, and DOES NOT cause the "check fuel" warning light to activate!
ConsNone so far.

Locking Gas Cap
March 13, 2014
Sometimes the lock will not turn and it takes a while to get off.
ConsSometimes hard to unlock. I think key should be longer and lock not as sloppy. I would only recommend this because there are not many alternatives. Also should have a teather.

Locking Gas Cap
March 9, 2014
The locking gas cap is just that, a gas cap that locks. It didn't say mopar on it anywhere. Just a big S. Made in Mexico.
ProsLocks, is a gas cap.
ConsOver priced, made in Mexico, not sure if Mopar actually makes it or has someone make it for them.

Satisfied Customer

This is the second time I ordered this item. I forgot to put the cover back at the gas station and drove off while the cover was on the bumper. I'm truly satisfied with the item. The ship time to the island was expedient via USPS.
ProsEnsures safety and tamper proof.
ConsNone yet.
