Multi-Size Faraday Protection for Key Fobs
The ZM-SJB-803 family covers every key fob size — from compact car keys to large smart fobs — with shielding-fabric-lined pouches from 8 cm to 14 cm. Sealed inside, the pouch is designed to block the fob relay signal — a countermeasure for keyless-entry relay theft.

• Shielding fabric lining; carbon-fiber-look or colored exteriors

• Also fits contactless cards and small devices
• Custom logos and size sets for dealerships and retailers; no MOQ
How to Choose a Size
Measure your key fob and add 1-2 cm of clearance, then pick the pouch whose inner dimensions fit. The fob must sit fully inside with the flap sealed — a partial closure leaks signal.
Ask for the size chart, attenuation data and custom logo options — standard items ship with no minimum order quantity.
