I just tried this with no luck (2008 E92)

Kinda on subject, you could add a remote start and they have keyless take over. Meaning that you wont need key in the ignition to drive away. But you will need to start the car with the remote starter for this to work.

For security the car will shut down if not unlocked with a remote, so someone cant just get in and drive away. Even if say the car is started with windows down and someone gets in and unlock doors with switch, car will shut down as soon as clutch or brake is pressed.

Anyways this would kinda be a keyless system.

As for the comfort access i've found that different cars use different number of antennas like the 7 series uses 8 and an e90 uses 4 but on real oem it shows my e70 uses only 2 antennas. In 2020 you can get all parts used for around 300-500 all you have to do is figure out the wiring from all the sensors to the the passive go module and from that module to the cas.Basically the module has 3 wire CAN signal one fused power and one ground, rest are all the wires that go to the sensors and door handles. the cas does not need to be changed or whatever the bs these guys are talking in the previous comments. all you do is program the passive go/CA module to your vin with winkfp, then go into ncs expert and code the CA to cas and frm like e90 or e70/ cas or lma like e60. once programmed you'll see the CA module show up in ncs expert, next you write a blank file to that module in ncs expert and all should work.

I want to do CA but I dont give a fuck about the door handles, I just want CA so I can start my car without putting a key in. Do you think its possible to just do the Antennas and the module itself and resistor the handles out so I can only have the Keyless start.

First of all the post you quoted is complete nonsense so please don't take it serious.

It should be possible to use the CA module without the handles / bumper antenna. It most likely wont even show an error on the dash. Using a resistor to "disable" the error wont work since they are connected via bus.
I have retrofitted CA to my E91 and it is not a hard as one might think.

Right I have an E91… just got it, I have read most of this thread BUT it kinda hasn’t answered my question…

Is there ANY WAY and if so HOW can I start my car with my fob in my pocket and not in the slot….. and on a scale of 1 to NOPE! How easy is it for a stupid human????

It's a pretty involved retrofit, and you wont have much change out of £1k

Ok so where do I start?
