Problem:
It’s a Range Rover Sport 2019. Trying to add a spare smart key with Autel IM508 and Autel’s universal Land Rover key. Cloned key successfully, remote works and car starts only when put key near sensing area. Proximity does not work. How to make the proximity to work?
Solution:
These models’ UWB ((Ultra Wide Band)) function is enabled. All current Land Rover models employ ‘Ultra Wideband’ (UWB) technology within the vehicle’s Smart Keys. This is normal if keylessgo is not working.
Almost all tools use the same solution for these vehicles, reading key(s) from the RFA and emulating them into change-ID or their own keys. This is fine for places outside of the EU/AU that use non-UWB keys.
UWB equipped vehicles require one of several solutions, one is to use the emulated keys & alter the CCF to turn UWB off. UWB is a setting so it’s a frequency setting on those newer vehicles you have to turn it off when you’re not using a OEM key cuz the key is not capable of ultra wide band.
You can turn off ultra wide band after you make a new key if you use a clone style key to get the remote wireless functionality back.
Lonsdor K518 Pro also has a function to disable UWB.
Go to Lonsdor Modify vehicle config function.
Disable UWB function.
Then check if the key is working properly.
However this has the side effect of disabling telematics and navigation as they are linked to the UWB function in GWM & BCM. This also removes part of the security solution for these vehicles.
Another is to use a UWB emulator like Abrites do, this won’t fly with owners of these vehicles until they’re much older than they are now, soldering a tiny, cheap PCB into an expensive car is not a good look. Once again however this removes a part of the security solution.
The real option for JPLA/K8D2/M9R3 etc is to remove the RFA and replace it with a new unit and then code new keys to it and link the RFA to the car. Full keyless only with new RFA or new MCU.
If the car can be unlocked by holding the door handle =PSPS=Passive Entry Passive Start =keyless entry function. You have to replace the RFA unit or MCU chip.
Always check vehicle and KVM information and verify if KVM (RFA) is locked or not.
You can check KVM information using Lonsdor K518 Pro series devices.
Go to Immo& Remote->Jaguar-> Select from vehicle-> Jaguar (2018-)->Smart Key->Read vehicle info.
If it is a Land rover, go to Immo& Remote->Land rover-> Select from vehicle-> Land rover(2018-)->Smart Key->Read vehicle info.
If the RFA is locked, you cannot clone key to add a spare key.
The KVM has SPC MCU, which have to be changed in order to add key.
Or replace RFA with new unit, but in doing so you are hoping it has not had the BCM locked at the dealer as if BCM is also locked then you need to replace BCM as well, and put telematics unit into service mode.
