At last - there is a way to do this. I've done it on my 2013 F-Type and it works fine. I'm not bothered about keyless entry and it's a huge theft problem now.

What is Relay Theft?

Relay Theft is the process criminals use to steal a car with keyless entry. Firstly, they buy a relay amplifier and a relay transmitter; these electronic devices can be purchased easily on the internet.

Next, they identify a house with a nice car parked outside and by using these devices, one criminal then stands by the car with his transmitter, while a second, with his receiver walks around the perimeter of the house. If the car key is close enough the receiver will detect its signal, amplify it and send it to the accomplice’s transmitter.

The accomplice’s transmitter then effectively becomes the key, and the car then thinks the real key is nearby, where upon the thief is able to open the car, get in and drive away. The whole process can take as little as 60 seconds and can be completed in near silence.

With the keyless system switched off it is impossible for someone to open your vehicle using this method.

1. Open driver's door (using fob)
2. Key fob inside car
3. Press headlamp button on the key fob 3 times
4. Press unlock button on the key fob once
5. Keys outside car
6. Close driver's door
7. Lock car using the fob
8. Unlock car using the fob 

Same procedure again to re-enable it, except press the lock button at step 4.

You have to make sure (i think) you first unlock and then re-lock the car with the fob, not the keyless button on the door.

Your car is now more secure.

Does this also disable the keyless lock and alarm setting? Where you push the handle in twice and it beeps, same as if you press lock button on fob twice? I would assume so but just checking.

Actually it does.
If you drop Rob a pm and ask him to make it a sticky I'm sure he will oblige.

I love keyless entry and won't switch it off. Surely it must be easier to have a Faraday pouch or box such as this in the house, simply slip the key in when you get home.

I've just bought a 2014 V6S and have been trying to disable keyless entry using the above but no joy.

I'm tech-savvy but this just isn't working for me! Tried it a few times but no luck. It's pretty straightforward so if anyone has any ideas what could be wrong I'd be grateful to hear!

I've bought a pair of Faraday pouches from Amazon. Less than £10. They work a treat. Stood right next to my car door and handle did not open.

I've got a couple of them too but not really practical for me and I'd rather just disable keyless go but not have any luck so far
