Ford Focus Keyless 2012

[Manta1600]

Few months ago I had Focus 2012 keyless with 2 original keys that start the car only emergency

Someone deleted the keys and tried to reprogram them back and fail as the car wont see the keys when must press the button on the remoete

Both keys has good signal I also tried few other keys

Today the gay call me that he replaced the sensor that is on the ceiling 6G9T-15K602-BA and I programmed sucessful both keys back

Now the keyless entry and the remote work but the keyless start again wont work

The sensor that he replaced for sure is about the remote but is it there other sensor about the keyless start?

Also on the original sensor the last 2 leters are different but the sensor coming from exactly the same car

This is an interesting thread.
I will keep an eye on this one.

For this case, you have to looking for tech diagram.

Here is the link with all the keyless entry and start components:

There should be one high frequency antenna for the remote, one or more low frequency antennas for the keyless entry usually on the outer edges of the car, one antenna for induction reading (on the steering column or below the cup holders between the seats), and one low frequency antenna for keyless start also inside the cabin. The last one is most likely the one you need. Like most antennas you should be able to check the resistance between the connection ports and compare them to nominal values online to check if it is working properly.
