Program 2018 Mustang Key with Key Tool Plus and Ford Bypass Cable

 We are looking at a 2018 Ford Mustang.   The situation was a locksmith came out here and somehow managed to clear all the keys out and then they couldn’t add keys back in had an active alarm situation.

My first time actually trying the Xhorse ford mustang alarm active bypass cable but it worked like a charm.

What i had to do is unhook the positive lead connect this orange piece to the positive. Connect read to the battery.  Now the battery was low so then i also has to put a jumper box on the positive lead and then just to the negative terminal to ground it out to get enough juice to program the keys.

Then just simply plug the cable into your OBD connector and then into your OBD2 port.

The cable definitely not work with mini obd tool.  The programmer has to have its own power. And the mini OBD requires power from the car.

You also have to latch the door so the car thinks the doors are closed. It says just to close driver door but i had to open the passenger door as well because the cable was not long enough to reach the battery because it’s on the passenger side of the car so i pushed both latches in on both sides.

So the car thought both doors were closed. I went through a little 10-minute process and it programmed the keys right in one try.

Also i’ll throw a connection diagram, just so you can see the connections but the vvdi key tool plus also has a pretty good picture.

I did the 2018 Mustang with an active alarm so i am actually pretty impressed with it.

Connection images are attached below:

Xhorse Key Tool Plus Failed to Read Discovery3 CEM?

 Q:  Trying to do Land Rover Discovery 3 All keys lost via xhorse vvdi key tool plus prog immo but cannot find option for discovery 3 prog immo option.

Solution:

You need to read it with VVDI prog. Discovery 3/RangeRover Sport CEM. You need to remove a component and put a 10kohm resistor in line.

CEM read function is not there.. Not all vvdi prog functions are in Key tool plus.

Keytool plus cannot read PIC from CEM. Use vvdi prog. Then make dealer key with keytool plus.

A similar procedure goes like this:
