OBD-II port/tune saver. This tune saver is designed to keep unauthorized persons from accessing your '96 and newer computer through its OBDII port. It prevents such things as changing programming, changing performance parameters or accessing vehicle specific data such as key codes.

This may work on other vehicles with an OBDII port but we cannot confirm any model other than Ram trucks.

Ecellent OBDII Port Lock
Jan 10, 2022  |  By SuperDave
You won't find many OBD-II port locks on the market, especially ones like this that are reasonably priced and made of metal (not plastic). Geno's was great to deal with and answered all of my questions on the phone. Ordering a second port lock for my other car!

Just bought 2 of these, one for a Highlander and a Tacoma. These are beautifully machined aluminum. They have a clever lock system, that is very pick resistant. 10 second install. Nice to have peace of mind that your vehicle is more protected from being hacked and stolen, via the OBD port.

Excellent Product

Arrived a few days after ordering. Took all of 1 minute to install on my 2021 Jeep Grand Cherokee. Peace of mind.
