How Car Key Fob Works?

A key fob is usually a remote control device used to control a remote keyless entry system, whether it’s your home, business, or car. These systems are digital keys that provide access without using an actual key. At Diego’s Locksmith, we can help you enjoy the convenience and enhanced security that the fob provides. It can be frustrating and inconvenient when you have misplaced your car keys. That’s why our car locksmith can help you alleviate this problem through key fob programming, ensuring you gain access to your vehicle within a moment’s notice.

Fobs and Radio Frequency Identification (RFID)

These systems perform their locking and unlocking function via a built-in RFID system. This barcode system uses an electromagnetic field to identify or locate stored information referred to as tags. The tags relay the information to the fob device using radio frequencies. Like a credit card strip, the RFID provides secure information to the fob, which gathers the information provided by the tag. Once the information the fob is requesting matches the information from the tag, then the locking and unlocking function occurs. The only difference between a credit card reader and a fob is that neither the RFID nor the fob must be stationary for frequency transmission.

The Key Fob Programming

When it comes to key fob programming, then Diego’s Locksmith has got you covered. Our professional locksmith will usually commence configuration using a microchip with an imprinted code. Every chip has an assigned frequency that communicates with the reader, opening the door when the frequency and code align. This means that the unique code in every fob opens only one specific door unless you request the manufacturing of multiple fobs with a similar code. Diego’s Locksmith can help you with multiple key fob programming if this is the case.

The Fob’s Locking Mechanism

Every remote reader system and fob requires a security measure that denies or grants access to a particular door lock. Most manufacturers enhance the level of security by implementing a locking mechanism. When a user pushes the button on the fob, and the mechanism doesn’t sense a match, the lock doesn’t open. However, the expert from Diego’s Locksmith can conduct key fob programming to ease communication on an open-access platform. Our talented locksmith can program a single fob to communicate with several devices, giving multiple users access to the same door.

When it comes to your car, key fob programming can be used to create a backup key fob that has a similar code, so there’s easy access to the vehicle even when the original fob has been misplaced. It also comes in handy when multiple people can use a car since each person can be provided with a matching fob for easy access to a facility or car.

At Diego’s Locksmith, we recommend this type of remote access because of the enhanced security and convenience it offers. Contact us today and talk to our professional Locksmith if you consider switching to remote entry.
