Retrofit Keyless Entry

[Pliind]

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

I don't know what do you mean by antennas but I can tell you this. There is module in the trunk behind the plastic cover where the locking mechanism. If it is disconnected, the keyless entry and locking the doors from the push button on the handles  will not work at all.  So, disconnection of any of the components may be enough for the system not to work at all.

For keyless to work antennas need to be mounted, in the trunk its under the floor towards the bumper. So when you come close to trunk and press it and antenna recognises your fob, trunk will unlock
