Retrofit Keyless Entry

I want to ask . Can I install touch buttons in standard pens? If you install only 2 handles and 4 antennas. Will this work?

it will not work. There is a proximity sensor installed which has 2 sections - one from inside to open the locks (detects a hand put inside the handle) and second outside - to lock the car.
The sensor communicates with the car on the communication bus - I dont remember if it is CAN or LIN - does not matter - simple touch sensor will not work.

Thanks for the answer. Do I need to install 4 handles? 2 front ones won't be enough?

2 will work as long as you mount antennas in the back doors and trunk. You will get fault code for othe 2 missing handles though
