Replacement remote for Ford models

This 433MHz remote key fits Ford C-Max 2003-2008, Fiesta 2001-2010, Focus 2004-2008, Fusion 2001-2012, Mondeo 2007-2010, S-Max 2006-2010, Galaxy 2006-2010, Transit Connect 2006-2013 and Transit Courier 2014-2017. It includes the 4D63 ID63 80 bit transponder chip, battery and electronics. The three buttons match the original layout.

Performance after programming

Once programmed by a locksmith, the remote operates at 433MHz for reliable locking and unlocking. The circuit board and chip are built for stable performance over repeated daily use. The included button cell powers the transmitter without additional setup. Physical durability matches the original key fob design.

FO21 blade requires cutting

The key uses an FO21 blade profile that must be cut to match your vehicle's lock cylinders. Programming must succeed before the blade is cut, otherwise the key will not start the engine. Buyers without access to a locksmith who can program Ford 4D63 transponders cannot use this product.

Questions about this item

Does the 433 MHz fob draw noticeable power when left in the car overnight?

The remote uses a button cell that powers only brief transmissions; standby draw is negligible and will not drain the vehicle battery.

What must I already have to make the FO21 key blade work with my 2008 Ford Focus?

You need a compatible 4D63 (ID63 80 bit) transponder already programmed to the car and a locksmith to cut the FO21 blade to match your ignition.

Will this replacement remote interfere with the original key I keep for my 2010 Ford Fiesta?

Both remotes operate on 433 MHz with the same 4D63 chip type; once each is programmed they work independently without conflict.
