Has anyone heard of an aftermarket door lock system that unlocks as you approach the vehicle like in Mercedes and some new Mazdas like the CX-7 and the CX-9 have? I just thought that would be awesome to keep your keys in your pocket and have it automatically unlock.

These systems also allow the ignition to recognize your presence so it'll let you just use a push button start and off you go.

Just thinkin about puttin' one in my trans am

 

that would be awesome to have a chip in my wallet that did the unlocking and starting....

 

Ive wandered that myself, but Ive never heard of an aftermarket thing out there.

 

I'll take one, if anyone knows where to find it...

Hell, I wouldn't even have to carry my keys anymore!

 

I would be worried about the price being to high or the quality being to low.

 

Did a bunch of searching.. for passive keyless entry.

Can't find anything good, really. Probably best bet is to grab the stuff from a production car, or buy the modules from a dealership *shrug*

 

My buddy has a new Lexus LS350 with this setup, and its trick for sure. I couldnt imagine what the cost would be just for parts.

 

here's something I found, and it's not too expensive either

Not sure about the quality though. And this doesn't let you start the car, it just locks and unlocks the doors as you approach/walk away from it
