Summary
It will completely shield your electronic car key. So much so that even if you put the key in the pouch after you opened the car and insert the key into the ignition, it won’t start. That is quite impressive. If you worry about your vehicle getting stolen simply via hacking your key-fob, this immediately makes it impossible. That alone is worth investing on and we highly recommend it. Aside from the velcro that can get a little annoying at times, it is all good news about this item, it just works.

( votes)MONOJOY Signal Blocker Case
Keyless entry car theft is a very real issue, with expensive models in built-up areas particularly at risk. The number one way to prevent keyless entry theft is to stop the key from being vulnerable by blocking the signal. It is here where the MONOJOY Signal Blocker Case becomes such a useful item. Thieves use relay devices (which you can easily buy online) to amplify the signal from the key fob in your home to a transmitter near your car. This essentially tricks your car into thinking the key is present.
This allows them entry into the car, where they can use the start-stop button to start the car without the key. The key also doesn’t need to be present within the car for it to continue running – so they can keep driving as long as the ignition isn’t turned off at any point.
If you don’t want to put your faith in physical solutions like steering locks, then Faraday bags are a good preventative measure. They work by blocking electromagnetic fields, which stops radio frequencies from being amplified – meaning your car can’t be stolen without the physical key.
The 20cm x 10cm Monojoy pouch is a great, cheap bit of kit for anyone who’s worried about waking up to find their car stolen. And with this purchase, you get two pouches.
The MONOJOY Signal Blocker Case is pretty small, meaning our car key fob fits inside, and you could get a house key or another key fob in there as long as they aren’t massive. The RFID blocking material also means that technically you can put building access keys, smartwatches, etc in there to protect them too.
Considering the rise in keyless entry theft, the size of the bag is also good because it means you can put it in a pocket or bag and carry it around with you. This prevents thieves who wait for you to park and leave your car before blocking the signal, meaning they can get into your car using a signal extender even after you’ve walked a few hundred metres from the vehicle. With keys inside the pouch, it can be a bit bulky for a pocket though.
The signal is completely blocked inside the MONOJOY Signal Blocker Case pouch, so even if you put it in your pocket and the buttons get accidentally clicked, your car won’t unlock. The only downside is that the velcro can be a bit annoying, something a bit less basic might have been a nice touch considering the velcro pulled the wool off one of our jumpers…
If you’re worried about your car being stolen then it’s a great investment. For the small price you pay, the MONOJOY Signal Blocker Case gives you peace of mind about leaving your keyless entry car outside your house. Even if you don’t have a keyless start, those who can gain entry can steal anything you leave inside your car.
