Have a read of this;
https://www.golfgtiforum.co.uk/index.php?topic=282638.0Assume you’re concerned about the potential risk of theft of your car. Rather than permanently disable keyless, why not consider other options;
- Faraday pouch or small metal container that can be closed to keep your keys in.
- visible physical protection such as a Disklok or Stoplock Elite Pro.
From what I’ve read on the Golf R forum, pretty much any thefts of forum members Golf R’s on that forum has been as a result of the perpetrators breaking into the car owner’s house and stealing the keys, rather than by intercepting the keyless signal with signal booster amplification equipment.
To minimise the risk of key theft from your house, it might be worth reviewing your home security. Also, if you have a garage that’s large enough to get your car in but the garage is currently used to store junk, then take the opportunity to have a clear out and garage your car when it’s not being used - if would-be perpetrators can’t see it then it removes temptation; out of sight is out of mind.
