## Questions & Answers

**Q: Compatibilidad para conector obd mitsubishi?**
A: Thank you for your question!  The cut profile inside the lock is only compatible with the profile of the OBD-II connector.  You will have to check product photos carefully to determine compatibility.

**Q: Would this fit bmw x5 ?**
A: Thank you for your question!  You will have to view the product photos to check for compatibility.  If you have the OBD-II port on your vehicle, the port will physically fit inside the inner profile of the lock, but you also need clearance to fit the outside dimensions of the lock.  The product photos should show you what sort of clearance is required around the outside of the lock to ensure compatibility.

**Q: Is this metal or plastic**
A: The unit is anodized aluminum with a stainless steel locking component.

**Q: Does this fit a 2024 Lexus NX 350h?**
A: Thank you for your question!  You will have to look at the product photographs to determine compatibility with your vehicle.  If you have the OBD-II port, the inner profile of the lock will fit that port.  If you do not have the clearance to fit the outer dimensions of the lock, as the clearance shown in the product photos, then this unit will not be compatible with your vehicle.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good design, but appreciate its limitations.
*by A***P on August 9, 2024*

As other have said, if you are using this as part of an effort to defeat thieves, it isn't perfect, as a motivated thief could jam a screwdriver into the tab window and pry the Tune Saver off.But, that would have to be quite a motivated thief who recognizes the design and is willing to spend the time and potentially break the OBD port along the way.One suggestion: Once you have the Tune Saver locked on, cut a small piece of black electrical tape and put it over the tab window on the sliding piece.Otherwise, while nothing is going to defeat a professional thief who really wants your car, here are some other options to slow thieves down or give you a chance of early recovery:1. Keep your keys in a Faraday wallet.2. Hide some AirTags in the body and interior areas, using TagVaults. Clip the speakers out first.3. Use a Club; face it toward the dash.4. Install a hidden kill switch.5. Move the real OBD port elsewhere and leave the original as a dummy.

### ⭐⭐⭐⭐⭐ Costly but worth it to me
*by T***Y on August 19, 2024*

Used this on a tuned aftermarket modded s550 Mustang so the dealership doesn’t brick my car. Fits perfectly. Easy to use. Solid. Does what it’s supposed to. I have taken it on and off multiple times and I see no signs of wear to the lock or the port. Expensive for what it is but there doesn’t seem to be a lot of great options out there. One time I took a car in with a simple tune and no other mods. I removed the tune before bringing it in. I told them “don’t put software on my car”. I came out and my car had a new version of factory software. It took me upgrading my tune and tuner to fix it. It took hours. This little thing would have saved me a lot of time and aggravation.

### ⭐ BEWARE - Does NOT fit any Honda vehicle that I tried it on!
*by R***O on April 11, 2025*

Beware! This OBD II lock does NOT fit Honda’s. This is due to the two internal bevels that can be seen in my first picture. I tried it on my 2019 Honda Pilot Elite as well as our new Honda Civic CR-V Hybrid Sport Touring. It’s a shame because the item is made out of stainless steel and would be difficult to defeat. I’m not sure what type of vehicle that they designed this to fit.
