Directed 452T

this is a very good upgrade for my Toyota RAV4. It's a cheap and easy install to automate door lock.

I installed this product myself in my 2005 Honda Pilot. It has worked flawlessly for over 6 months now locking/unlocking my vehicle from park to drive.
I figured at this great purchase price if It should fail, I'd simply buy another one. So far absolutely no problems and I don't foresee any.

Thanks, Sonic Electronix.

I'm using the 452T as a door lock pulse generator in my Toyota RAV4. The 452T is activated by the back-up lights so that shifting into reverse will automatically lock the vehicle doors. The instructions to do this are available at the RAV4World website. The 452T was easy to install, the instructions were clear. The 452T has been installed for almost six months now and has continued to perform as expected.

After learning of this product and its application on the RAV4World owners forum, I ordered to make my doors auto-lock. The unit was relatively easy to install (for a person with average knowledge) and worked as indicated. Now all doors lock when the vehicle is shifted out of PARK. The driver's door unlocks when shifting back into park. Nice sense of security!

Product works as advertised. On receiving a constant voltage one line is sent a pulse, when the voltage drops another line pulses.
