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

This OBD lock was easy to install and fits securely. It gives extra security for my car, especially when leaving it parked for long periods. The materials feel sturdy and the key mechanism works smoothly. A simple but effective anti-theft addition.

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.

Fit right on my 2024 ram promaster, build quality seems good! Nice piece of mind!

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.

While installation is relatively straightforward, it would have been nice to include at least a single page flyer describing it so that one doesn't have to go back and watch the video. Also while the milling of the actual lock is good the T-handle is terrible. The locking tool does not insert into the handle at all, no matter how you line it up or try different orientations, this is what you end up with. I am going to have to dremel it out to make it fit properly. Lack of attention to detail not worthy of the price they are selling it for.

I picked this up for some extra peace of mind for my 2025 Honda Civic Sport Touring Hybrid, and it fits well. Honestly, it does exactly what it’s supposed to do. If someone manages to break into the car, they are definitely going to have a much harder time trying to access the OBD port. It feels like a solid deterrent. I also really appreciate the included case for the key bolt—it’s a nice touch to keep that piece secure when it's not in use. That said, I’m giving it 4 stars because of the installation experience. The price feels a little steep for what it actually is, and the install itself was a bit frustrating. The "T" tool doesn't really snap or lock into place firmly, so it feels a bit loose while you’re trying to maneuver it. A word of advice to anyone else buying this: Be extremely careful when handling the two tiny screws and the key bolt during installation. They are very easy to drop, and given how small they are, they’d be a nightmare to find if they fall into your floor mats or under the seat. Overall, I’d recommend it, just take your time with the setup!

Excellent quality product and very easy to install. Is a little more expensive than other brands but I was sold on the unique custom-made security screws. I would highly recommend to friends and family.

Very recently, I came outside to find someone had attempted to steal my car (2025 Honda CRV hybrid). They used a relay device to gain access to my car without forced entry. They removed the plastic dash trim part to get access to the OBD port with intention to clone my keys to quickly steal it which is a thief method targeting Hondas. What they didn’t expect was to see this lock. Photos shown are from the aftermath of attempt to remove the OBD lock. They tried to pry it off but completely fail. The lock remains fully intact and does not budge even when I tried pulling it myself. I am thankful this cover held up because without it my car would be gone. I live in Philly and parked my car on a busy residential street. Based on how cleanly and efficiently they gained entry with zero evidence of forced access, this was likely a professional crew operating as part of an organized car theft ring. These crews operate on speed — typically under 2 minutes — and this device completely disrupted their routine and made the risk not worth it. I cannot speak to someone with unlimited time and specialized tools, but for the smash and grab professional crews targeting Hondas right now, this will absolutely stop them. If you own a Honda CR-V, Pilot, or any Honda with keyless entry — buy this immediately. It is the single best investment I have made for my car’s security.

Has been heaps of car theft on push button start vehicles using lo-if RF attacks boosting your key fob signal while you sleep or a more common method of CANbus attack by reprogramming a new key via your OBD2 port. Either way, car is gone in less than 60s with readily available tech off Temu. Did my research on OBD port blocks and this is the best on the market. Quality CNC machined parts to an almost tolerance fit, and unique security keys in rotation. Would be very hard to get off without the unique key or destroying the OBD port plug. 100% recommend this, plus get yourself a faraday box for your keys at night and a club lock for your steering wheel.

Great seller. Fast shipping. Product looks of good quality and well thought. It is expensive for what it is. Hoping this will be strong deterrent.

Ik heb bewust een niet-GM model gekocht voor mijn bmw, maar helaas past deze er niet op. VTT OBD-lock ziet er verder goed uit, maar helaas niet de juiste pasvorm.

Prompt delivery, very impressed with quality , well worth spending the difference compared to the cheaper OBD port locks on the market . Easy to fit even when working in the footwell . Took about three minutes to fit after watching a YouTube video - I would definitely recommend watching the video first for some really useful tips . Good sized window sticker as well to act as a visible deterrent

Del'd as requested !.. Excellant quality .. easy install ..great response from seller on a special request.I'd recommend this product and this seller! 5x5!
