Key Differences: Why Our Key Fob Enclosures Stand Out

We’ve designed our key fob enclosures with must-have features that set them apart and make them a premier choice for so many different applications. What is it about these features that makes them so important?

Built-In Keychain Ring: The ability to clip a key fob onto your keys is so important that it’s even part of the name. A molded-on ring makes it simple for homeowners, employees and business owners to simply clip their key fob onto a keychain or carabiner.
Durable Construction: Key fobs must survive being regularly dropped, exposed to hot and cold temperatures and jumbled around with heavier objects. We create our key fob enclosures from ABS plastic, a rugged and reliable material that’s tough enough for everything from car key covers to industrial and commercial access badges.
PCB Capture: Nearly all key fob devices use a printed circuit board, which means most key fob cases require mounting bosses and standoffs to hold the circuit board in place. With the built-in PCB mounting hardware of Polycase key fob enclosures, there’s no need to purchase extra hardware — just seat your circuit board in the case and snap or screw it shut.
Button and Battery Options: Many key fobs require features such as built-in buttons and coin cell battery compartments. Polycase’s enclosures include robust options for buttons and battery cases, saving you the expense of having them custom-fabricated by a third party.
In-House Customization: We also offer the ability to customize all of our key fob protector cases using state-of-the-art CNC machining and digital printing. Create highly accurate custom cutouts on your key fob or add crisp and colorful images and text using our digital printing service. Our extensive in-house capabilities allow us to provide fast turnaround times and minimal scrap costs, and it’s easy to get started with an instant quote on your customized enclosures.
