MechanMagic Honda Civic Key Fob Remote KR5V2X 5-Button (2016–2021) Pre-tested, Uncut 433MHz

MechanMagic's 5-button KR5V2X smart proximity key fob is a ready-to-program replacement for 2016–2021 Honda Civic push-start models, pre-installed with electronics and battery.

If your Honda Civic's original proximity remote is lost, damaged, or no longer communicating with the car, this MechanMagic key fob is built to match the factory-style convenience. It fits FCC ID KR5V2X(V44) and replaces part numbers including 72147-TBA-A11/A12, offering an uncut emergency blade and pre-tested electronics so installation starts from a reliable, out-of-the-box component.

How will this key fob match my Honda Civic?

The fob is engineered to be functionally equivalent to OEM remotes used on Civic EX and LX models with push-button start between 2016 and 2021. MechanMagic supplies the correct transmitter frequency (433 MHz) and the same FCC ID reference so trained technicians can proceed with cutting and programming.

• Compatible FCC ID: KR5V2X(V44)
• Replaces part numbers: 72147-TBA-A11, 72147-TBA-A12, 72147-TBA-A121-M1
• Frequency: 433 MHz; Chip: 47
• Includes uncut HO01 emergency insert blade

What does “pre-tested” and “ready to program” really mean?

Each MechanMagic remote is inspected with professional locksmith tools before shipment so the battery, circuit board, and transmitter work correctly out of the box. Pre-testing confirms the fob will respond electrically, reducing return risk and making the next step—cutting and programming—straightforward for a locksmith or dealer.

• Electronics and battery installed and verified
• Transmitter signal validated by professional tools
• Shipped as a 100% new, uncut unit ready for key cutting
• Emergency blade included for manual entry if required

How do I get the fob cut and programmed to my car?

This fob requires professional cutting of the emergency blade and programming of the transmitter to pair with your vehicle’s immobilizer and proximity system. Dealerships and qualified locksmiths have the necessary key blanks and programming equipment to safely integrate the new remote with your Civic.

• Not a self-programming remote—professional service required
• Bring vehicle proof and original VIN to a locksmith or dealer
• Technician will cut HO01 emergency blade and program keyless entry
• Supports push-button start / proximity systems only

What comes in the box and what should I expect after purchase?

Your package contains one MechanMagic 5-button smart proximity remote with electronics and battery pre-installed plus an uncut emergency blade. Expect a brand-new, factory-style fob that still needs cutting and programming to become fully operational with your car.

• 1 x 5-button smart proximity key fob (electronics & battery installed)
• 1 x uncut HO01 emergency insert blade
• 100% uncut — ready for key cutting and programming
• Transmitter-only; does not convert regular keyed models to proximity

Who is this for: MechanMagic's replacement remote is designed for Honda Civic owners (EX, LX) from model years 2016 through 2021 who need a like-for-like proximity key fob—whether the original is lost, malfunctioning, or being upgraded. It's ideal for vehicle owners who will use a professional locksmith or dealership for cutting and programming, and for DIYers who source those services separately. If your Civic uses a traditional keyed ignition rather than a push-start proximity system, this transmitter will not be compatible.
