Ford Explorer Sport key types & programming facts
2002-2003 Ford Explorer Sport models use a standard transponder ignition key and a separate keyless entry remote fob. Programming of the remote fob can be done through an onboard procedure using ignition/key cycles and the factory keyless entry system. Transponder key programming typically also uses an onboard procedure that requires existing working keys, or dealer/locksmith equipment if no programmed key is available.
Key types used on the Explorer Sport:
- transponder chip key (separate metal key plus stand-alone remote fob) (2002-2003)
Common fob FCC IDs: CWTWB1U331, CWTWB1U345, CWTWB1U212, GQ43VT11T — check the back of your fob; we confirm the exact variant on site.

How we validate this guide
Year coverage comes from our consolidated vehicle programming dataset. Route-level programming status is reviewed against internal route sheets and available manufacturer, security-access, and professional tool references. Exact button sequences are marked source-verified only when we have year/equipment-specific support; where a year is labeled “route verified, steps vary,” we confirm the exact fob, trim, and prompts before programming. Reviewed for route and safety by Mohammad H. Abdelhadi, ALOA-Certified Master Locksmith.

Common questions
What type of key does my 2002-2003 Ford Explorer Sport use?
It uses a transponder ignition key with a separate keyless entry remote fob, not a flip key or proximity push-to-start system.
Can I program a replacement remote for my 2002-2003 Explorer Sport myself?
Yes. The keyless entry remote can be programmed using the vehicle’s onboard procedure, following a specific sequence of ignition cycles and button presses.
Do I need a working key to add another key for my 2002-2003 Explorer Sport?
In most cases, at least one working transponder key is needed for onboard programming; otherwise a locksmith or dealer must program keys with diagnostic equipment.
Can you program a Explorer Sport key fob without going to the dealership?
For most years, yes - the route is onboard relearn or an OBD tool, both of which a mobile locksmith handles at your location.
Does this program the remote only, or the transponder key too?
It depends on your key type. Tell us your FCC ID and we will confirm.
What if my year says professional programming required?
Those years need a programmer or security access; we bring the tool to you and program it on site.
How much does it cost?
It depends on year, key type, and whether you have a working key. Call (833) 439-8636 for a firm price before we dispatch.
