Add keyless entry
Hi,
I Have W205 C200 2019 with Keyless Go but Not Keyless entry.
What parts I need to change to have keyless entry feature, at least the driver's door?
Door handle? receiver? remote key?
Please advise.
Thanks,

I assume you mean you have Keyless Start and want Keyless Go.
Keyless Go is very complicated. There are antennas all over the car, for instance. That's how it knows where the key is and prevents you from locking the keys in the car. Here's a description of an old version, but it's gotten more complex over time.

Because of the security implications, it would be very difficult to get a hacked set of components to be accepted by the car. At a minimum there would be a lot of coding involved. It's one of those upgrades that would be more expensive than selling the car and buying one that has it.

I have the push button to start the car, but not the hands free access to the car..
the door handles don't have the sensors..
the manual you sent seems very old, I believe I have those antennas, as I cant lock the car while the key is in anyway..
So what do I need to do here? just change the door handles?

It's easy to retrofit the doorhandle and costs like $190 for one keyless enttery doorhandle, but the thing is I don't know if it requires activation with coding, or if it is plug and play with keyless go cars. I can give you a link if you want, then you can ask the seller, about that

Hey guys sorry for the late reply, things have been hectic lately. Anyway, I spoke to the seller, he said that the kit he sells is plug and play and doesn't require any programming if you have keyless go (push to start engine). He is a decent seller that won't bail on you and will answer all your questions, I bought from him again and again, he even gives me discounts everytime I buy from him, and ships fast. Here's the link: https://a.aliexpress.com/_dWNa5Ou
If you want to push the trigger on retrofitting the keyless entry feature, do it soon since there is a discount going that takes $50 off so it's only $199 with free shipping. Just make sure you contact him to confirm your year and tell him Wail sent you, he might even give you a small discount extra. Good luck with this guys.

Anyway. Did you manage to install it? Does it work fine?
The seller told me:
-it is plug and play, no programming required (it comes with the controlling box that goes originally placed on the left side of the trunk)
-it will work with my current key as it is keyless go capable (car is from 2017) working at 433mhz
-I've been told that even the push start button would work so I bought one from AE for 9$
Can you confirm any of the above??
I will comment here once I get mine installed too

I haven't bought it myself, I just tried to help the OP who asked for it yet didn't really do anything once he got answers. I find this to be a n=nice to have gimmick rather than smtg I'd hate not having, since it's basically the same thing, tho the start-stop button imo is a must have. To answer your question, yes the start-stop button you bought from AE is probably going to work, based on what you're saying, it's pretty cheap too so no reason not to have it. If the button works, then the door handles will work too. Please post about your progress in this thread so if people come looking for it in the future they'd find answers.

For now I uploaded the manual of how to install this kit in a A177 car. The guide should also be valid for W205:

Not yet. I'm still waiting for my package to arrive (90 days and I think it's lost somewhere...)
However I found out that:
-These Chinese kits are meant to be installed in cars with keyless go already installed (the push to start button)
-This is not plug and play, even if you have the start button, it still requires coding if your car is pre face-lift (<2019)

I'll check with the local independent mechanic to see how much they charge to install these.

Problem is I only got 1 antenna and I think I would need at least one more (center console to detect when the key is inside the car + rear left door to detect when you approach the car and allow you to open it with the keyless door handle).
I also miss the keyless module which connects the all thing to the car CANBUS. But this can be found in Ebay for 40 dollars +-.
Will keep you posted if I get the parts I need and go ahead with the install.
Ps: of course this also needs programming via OBD to enable the keyless functionality

I received the package form China with the door handle with exactly the same colour as my car so I won't have to paint it.

Awesome, thank you. That's all i really want anyway, when i get sick enough to want to do the passenger door, so i can be a gentleman i will. But i like how the DRLS come on as i do it stealthy in my pocket from a far
programming shouldn't be too hard, but a lot of muppets on this forum are too scared to get a OBD2 to USB and start doing some coding to their cars modules.

GLC 250 SUV X253
Anyone tried this install and has good news? I got a handle, antenna, wires and obd tool from aliexpress for my 2017 GLC (my car has keyless start not keyless entry) and used the obd upgrade tool that works via Wechat (all translated from chinese using a second mobile phone with a google camera translation) and connecting to the obd tool from phone via bluetooth to select the car model in the tool. I have chosen the installation of 2 handles (I only have one) and the tool did its thing without errors. However, it did not work. I tried using Xentry/Das to monitor the status of the handle in the keyless module and it is showing the change of status when the handle is touched inside (open) and outside(lock). The Chinise handle therefore works but there is a programming problem or a problem with key codea. Xentry indicates error because the handle in the passanger side is not present. I have searched the forum and found nothing specific, only some people trying to make additional keys to work with KG and some posts discussing that the key track should be 1 and 2 to work with keylessGO. if anyone knows where to program additional parameters in xentry please let me know.
