I installed this little gadget in my 2018 Camry and wow – it's one of those 'why didn't I get this sooner' purchases. The automatic locking at 15km/h gives me peace of mind, especially when driving through sketchy neighborhoods or picking up my kids from school.

The installation was stupid easy – literally plug-and-play into the OBD port. No tools, no wiring, just push it in and forget about it. What surprised me most was how seamlessly it integrates with the car's existing systems. When I shift to P gear, there's this satisfying *click* as all doors unlock simultaneously.

One unexpected benefit? The flashing lights during reverse saved me from a close call in a crowded parking lot when someone wasn't paying attention. And that emergency brake unlock feature? Tested it accidentally during a sudden stop – doors popped open immediately like it was designed by Toyota themselves.

Pro tip: It works on way more models than just Camrys. My buddy installed it in his RAV4 with identical results. For under $20, this solves what should've been a standard safety feature from the factory.
