XPACK Signal Blocking Car Keys Holder Key FoB Anti-Theft Farady Bag RF Shield for Prevention of Signal Amplification Hacks

Totally blocks my key signal as advertised! Even if I am standing right next to my car, the key will not work unless I open the flap and partially pull the key out of the holder. So it gives me great confidence that my car is secure. Love it!!!!!

Bought two after my daughters car was hacked. Tested on two cars and worked intermittently. Was able to unlock for with fob tightly inside and sometimes not.

Didn't block signal

I have owned the Xpack key fob pouch or wallet (whatever you may want to call it) for a little over two months now. I purchased this to hold the smart-key for a new car. During the first month to month and a half any time I approached the car with the key concealed within the [closed] pouch the car would not unlock. Once in the car while the key was again in the pouch the car would not turn on. At that time, the key holder worked exactly how it was expected to work.After the first month to month and a half, the pouch started to allow the key fob's signal to breach. This is likely due to the constant opening and closing of the pouch to expose the key. When I initially noticed it was no longer functioning properly they pouch with the enclosed key would have to be very close to one of the car door antenna in order for the car to sense that the key was near. Once inside the car, the key could be in the pouch and the car would sense the key without a problem.While after two months, the key holder still looks great and there is no visible sign of wear, the electromagnetic field shielding fabric used inside of the pouch must have broken down after two short months of use. This is why I could only rate the product with two stars. Keeping in mind that the holder has never been wet or exposed to extreme temperatures. The failure occurred due to normal usage. I would consider purchasing future models providing more durable materials are used in the future.

After 6 months, it stopped blocking signal. I could literally walk up to my car, get in and start it... with the key in the pouch. Poor quality. Should have lasted a lot longer.

My son has a new car and is very protective of it so I gave this to him to use with his keys and was very happy with it so far, He is keeping on his belt using the clip that comes with it and so far it is working great at least I will say that he has had no break ins and makes him feel very secure using it. It is made of very durable material It Measures: 4.4 " x 3.15" x 0.12" (10.5 cm x 8cm x 0.3cm) , so not to big to put in your pocket or belt to carry it with you, It works with COMPLETE RFID BLOCKING SECURITY AGAINST HIGH-TECH CAR THIEVES: Lined with High grade RFID blocking material preventing all unwanted signal communications and signal amplification attacks to your keyless entry system. I will update later if anything comes up while he is using this .

Not worth

Clack Signal Blicking pouch is an excellent product to get protected. As described. It Is easy to carry. It's small, practice and elegant. I like the key chain holder addition. This is A plus.
