VTT OBD-Lock ODB Port Locking Tool (Non-GM Model) Version 2

A good quality OBD2 port lock made of billet aluminum that is anodized in red. I see some plastic made OBD port locks and would say to stay away from those. Some are even poorly 3D printed. This is one of the better ones out there. These have custom cut security screws that use a security bit to install and remove. Unlike typical security screws that use security bits that be bought at the local hardware store to use to unscrew, you cannot easily buy this custom security bit anywhere. It's good that the security screws change after so many sets of the locks are created. This can make sure that it's less likely for two people to have the same security bit for their lock. Someone won't be able to buy a lock and have a security bit that can unlock most of the locks.Like all locks, including the locks on the doors of your house, they are not undefeatable. With the right tools and enough time, anything can be defeated. The aim is to layer your security to make it harder or take more time for a bad actor.They are quite easy and fast to install. It even fits in recessed OBD ports. Just be careful when installing and removing so that you don't strip the threads or damage the nice anodized finish. The lock is made of aluminum so the threads can be stripped if they aren't lined up properly.They are on the pricey side, but not as expensive as another good OBD port lock I have.We asked VTT to send us their OBD lock to review. They sent one for free, we paid the import fees. See the video for more info on it.

My car was stolen (and recovered) a few months ago and it is equipped a push button start. I didn't realize how easy it is to clone the key fob for these cars and always kept my fobs in a Faraday box, figuring that I was safe from a potential thief. Its wasn't until I got my car back that I was told that thieves can also clone the fobs using the OBD II port.I looked at others before buying this one - it's pricey for sure, but worth it for the peace of mind as far as I'm concerned. I have a standard port on my car and it's mounted under the dash and not enclosed. I found installation easy, although at first it seemed a bit mysterious as to how this thing stays in place. Once you start trying to put it on it becomes pretty apparent though. Take note that if you have the type of port connector that is enclosed this may not fit.What I like about this lock is that it's metal and the fact that it uses an actual key, not just an allen key like a lot of others use. Anyone can get an allen key of the correct size but this is a unique key and not all of the locks come keyed the same - so it would be very difficult for someone to get a hold of the key.This lock completely encloses and protects the OBD II port and I can see no way to remove it without destroying the port connector, which, of course, would render the port useless anyway. I had no idea that there was such a thing as an OBD port lock and I'm glad I found this one. Highly recommended.

A snug fit! The “key” is very unique so it isn’t something that can be “picked”. It would be next to impossible for a would be thief to quickly remove this OBD lock without pulling the wires out of the back of the OBD unit.

Product is well made overall, just don't overtighten the screws and you'll be golden ! ( just wish the screws were of a stronger material, hence 4 stars and not 5 )

Fits Mercedes AMG GT 4 door (x290).No dealership would drill that off to update your software and a thief won't get those screws off without building some custom key tool. Expensive, but still less than half the cost of the dedicated Mercedes one I found, and serves its purpose beautifully, so I'm happy.

Worked great, installation took about 2 minutes. Great design and fit. I'll definitely recommend it to anyone looking for extra security.

Decent. Compact. Precision made, but that makes it very hard to install in tight spots. Fit my g80

The lock was easily fitted and is quite tight. It should be sufficient to deter thieves. The large red warning stickers on each side of the windscreen are clearly visible. Of course nothing will deter a thief if he has plenty of time, but this device should deter thieves looking to make a quick score.
