Why test it yourself

You can’t see a signal stop. You can hear a phone not ring.

Plenty of people get curious about signal pouches for a simple reason. Maybe the car key hangs on a hook by the front door, and you’ve read about keyless cars and started to wonder. Maybe you’d like your phone to be out of reach for an hour, without powering it down. Both are fair things to want, and both come down to the same question: does this pouch really do it?

The answer is yours to check, and you don’t need any tools. A sealed pouch has one job, so one call will show it. If the call goes through, the flap is the first thing to look at. Half closed doesn’t count. Press it down along its full length, then try again.

Once you’ve seen it work, it turns into a small habit. The car key goes in the pouch when you get home. The phone goes in when you want quiet. You’ve run the test yourself, so you aren’t taking anyone’s word for it. Repeat it now and then, the same way you’d try a door you locked.

Trust the call, not the label.

Before you buy

Check your phone, your case and your car.

Start with your phone. The pouch fits phones up to 6.5 in, and it’s about 7.75 x 3.9 in (19.7 x 10 cm) on the outside. If your phone is larger, or lives in a thick case, measure it against those numbers first. What matters is that the flap closes all the way with the phone inside.

Then think about your car key. If your car unlocks as you walk up to it, here’s a quick check. Seal the fob in the pouch, walk up to the car and try the handle. If the car doesn’t respond, the pouch is blocking the fob’s signal. Take the fob out when you’re ready to drive. Cars vary, so the test on your own car is the one that counts.

First use

Run the call test the day it arrives

1

Slide your phone in

Put your phone in the pouch. If a thick case stops the flap from closing, take the case off.

2

Close the flap fully

Press the velcro flap down along its full length. The pouch blocks signal only when the flap is fully closed.

3

Call your phone

Use another phone to call it. It should come up as unavailable. If it rings, reseat the phone, close the flap again and retry.

4

Try your car key

Seal the fob in the second pouch, walk up to your car and try the handle. If the car doesn’t respond, you’re set. Take the fob out to drive.

Repeat the call test now and then. If your phone still rings with the flap fully closed, send it back inside 30 days.
When to reach for it

For a key on a hook, or a phone you want quiet

Use it at home for a car key by the door. Use it on a trip for your phone and cards, or any time you’d like your phone unreachable without switching it off. You get 2 pouches, and the only setup is one phone call. If that call still gets through with the flap fully closed, send it back inside 30 days. Shipping to the US, Canada, the UK, Australia and New Zealand is free and tracked, and most orders arrive 1 to 3 weeks after ordering.

Layer your defense

The pouch handles the signal. The alarm handles the door.

A sealed pouch looks after what’s inside it. The next layer is the way into your home. Stuck onto a door or window, the TremShield Alarm fires a 125 dB siren the moment it’s forced. It needs no Wi-Fi and no subscription. One alarm is $29.99; six are $99, which is $16.50 per alarm (Save $80.94).

Questions, answered calmly

This Faraday pouch blocks signal when the flap is fully closed, and your phone goes unavailable. You can check that at home in a minute: seal your phone inside and call it from another phone. If the flap is left open, it won’t block the signal.

Put your phone in the pouch, close the flap fully and call the phone from another one. It should come up as unavailable and should not ring. If it rings, close the flap again and retry. For a car key, seal the fob inside and try the car door handle.

The TremShield pouch fits phones up to 6.5 in. It’s about 7.75 x 3.9 in (19.7 x 10 cm) on the outside. The flap has to close fully for the pouch to block signal, so a phone in a thick case may need to come out of the case.

Yes, this pouch can block a key fob’s signal when the flap is fully closed. Test it on your own car: seal the fob inside, walk up to the car and try the handle. The fob needs to come out of the pouch before you drive.

This pouch can block your key fob’s signal while it’s fully closed, and a relay trick depends on that signal. It can’t promise to stop every kind of car theft, and it doesn’t lock the car. Test it on your own car with the fob sealed inside.

This pouch isn’t sold as waterproof, so don’t count on it to keep water out. Keep it, and whatever is inside it, away from water as you would any phone sleeve.
