KESSY (only entry) installation to B8 Variant

[Ainer]

Hi,

Purchased used car and interesting thing is that from the factory only Keyless-GO is installed to the vehicle. No keyless entry.
"Central locking system Keyless Go without SAFELOCK" from the equipment list.

Has anybody installed keyless entry to the car? Can give some hints how much the car must be taken apart to install all original parts of kessy system.

New exterior door handles with the kessy support must be changed. What components else needs to be changed or additionally added?

SAFELOCK is a dead-locking system, it is not keyless entry. Basically, SAFELOCK disables the internal door handles once the car is locked.

I think there are also units inside the door that detect the key signal.

I think there are also units inside the door that detect the key signal.

2 (for front and rear doors) inner and 1 (for rear lid) outer aerials detects the key i assume.
I think that every door handle has own antenna for detecting the key, but not sure.
