I did a true life test and brought my new 2026 kia car keys down into the garage at the bottom of my 30 story high-rise. This saturday box type of bag totally blocked the signal. The second pocket in the front not the back pocket that is lined with the same type of material on both sides but the one in the front does not block the signal from the car keys. So use the back pocket only and it works like a charm

Since cars are easily stolen other people's driveways cuz when they get home they toss the keys into a bowl near the front door it's easy to scan for crooks and then they've got your car in under 3 minutes maybe even under 2 minutes. But put your car keys into the friday bag which is a signal blocking bag, and you'll be safe from that type of threat
