Here's a little info I gathered when looking for remotes for my vehicles and trying to determine if one remote could operate multiple vehicles.
2L3T-15K601-AA (2L3T15K601AA)
FCC ID : CWTWB1U331
CAN : 1788 104 575 (1788104575)
The 3 button (LOCK,UNLOCK AND HORN) keyless entry remote control will work with many different year and model Ford's, Lincoln's Mercury's and Mazda's Including:
1996-06 Ford Econoline Van E-150
2000-06 Ford Escape
2000-06 Ford Excursion
1998-05 Ford Explorer (2 Door)
1998-01 Ford Explorer (4 Door)
1998-06 F-150-, F-250, F-350
2005-06 Ford Freestyle
2004-06 Ford Freestar
1998-06 Ford Ranger
2000-05 Ford Sport Trac
1998-03 Ford Windstar
1998-02 Lincoln Navigator
1998-06 Mazda B2500, B3000, B4000
2001-06 Mazda Tribute
2005-06 Mercury Mariner
2004-06 Mercury Montero
1998-01 Mercury Mountaineer
I also have a 4 Button remote that works my 98 F150, 99 Mustang, 01 Sport Trac, 08 E250, my Moms 05 Escape an my uncles 03 F150. Therefore I suppose the above 3 button list, in its entirety, applies to this 4 button remote also. The 4 button remote bears these numbers:
2S4T-15K601-AA
FCC ID:CWTWB1U331
CAN:1788 104 575
