OBD-Lock ODB Port Locking Tool (GM Models ONLY) Version 2

Checked Camaro & Corvette forums for recommendations. VTT had the majority & it's a USA company so I went with them. Arrived quickly, is very solid & is super easy to install. Based on reviews, expected it might be tighter (harder to get on/off) around the OBD port, but still very secure. Now we can worry less leaving the top down when parked in public.

Works well and the installation took 3 minutes. Put the "key" bit holder on your Keychain so you don't lose it!

I have a 2021 Sierra 2500HD AT4. I’ve been seeing how quickly many vehicles have been getting stolen all from the OBD2 port and a tablet. I mean like in 5 minutes or less your ride is gone. That being said, $100 for this is a tough pill to swallow. However some peace of mind is worth it! I’d rather not deal with insurance on a trashed stolen truck worth 100K and get a check for “current market value” from insurance. This port lock is really well made. Great quality and machined wonderfully. I don’t know about version 1 of this product but version 2 is really made of nice pieces and a truly snug fit. I’d imagine if someone wants to steal something badly enough they’ll find a way. This however should slow them down for sure. They’re not going to be carrying the bits they need to get this off that for sure. If they want to mangle OBD2 in the process, they can have fun. Truly a well thought out product and a nice piece. Beats all the plastic ones I’d been seeing no doubt about that. Well done, VTT!!

Just what is needed to prevent unauthorized access to OBDII port. Should be eligible for an insurance discount!!!

Arrived a little beat up. T-Handle has some deep gauges. The Stop decal looks like it’s been wrinkled up and the flatten out. It has some hole in the middle of the decal. For $100 I was expecting better. The aluminum lock looks very sturdy and high quality. Updated 11/29/25 Installed on my C8 2022 Vette with no problems and looks solid. Decal was usable and damage isn’t that noticeable. Increased by 1 star. Note: Seller was willing to replace the decal if I provided a pic of damage and paid shipping for a replacement. I decided to see how it looked installed and just kept. I’d recommend getting this ODB lock.

Overpriced, identical to cheaper versions. The key also works between brands. So don’t depend on this to stop theft, but to slow them down and frustrate them until they give up, get caught, or trigger another layer of protection (immobilizer, alarm).

I Was in search for an anti theft device for my OBD-2 Port. But i didn’t want no cables to be cut for my obd-2 port. So i found this Product which blocks the OBD-2 port and its pretty Sturdy. GREAT FIT !! No gaps at all in my 2020 Silverado 1500. ONLY WAY THEY CAN TAKE IT OUT IF THEY BRAKE THE WHOLE Port which at that point theres no use . Yes it’s pricey and yes there is some that cost 40$ but this was the fitment that i was looking for. Like i said THIS PRODUCT DOESNT REQUIRED ANY HARD WORK. Took me 5 minutes to install . WORTH THE PRICE !

The GM-Only OBD lock does not work on all 2026 Models. Apparently no solution. I have passed return date so no joy. Very disappointed in VTT and GM.

Very tricky to install, but goes on well and would be difficult to remove without the tool!

Pretty expensive for what you get. But it is well made and fits securely over the OBD port. Is a good deterrent.

Quit item good service.

Good quality product, my version of the Holden Commodore are frequently being stolen, so any deterrent is helpful, easy to install

Worth every cent. Can never be to careful these days. Is quite fiddley to install on the VF Commodore and the key is hard to get line up on the bolts.
