Need entry key #49119 154-733 bought set didn't bring it (2 sets).

No that will not work

First you need to find the factory code, which will never change, On a 99' Ford Explorer XLT the code is in the trunk of the truck behind the plastic cover where your tire jack and wrench are, yours should be here too! There should be two plastic knobs that you will have to turn to open and lift it off, real simple. The code will be on the fender wall, bring paper and pen to write and will need a flash light so you can see the code clearly!!! The code is real close the the plasic and kinda hard to see. Next step is to set the code to your personal one.
1. Enter the factory-set code (keypad will illuminate when pressed).
2. Press the 1/2 control within five
seconds of step 1.
3. Enter your personal 5 digit code.
Enter each digit within five seconds
of the previous one.
You might want to set up your key/transmitter as well so it will work. To do this you must:
place the key in the
ignition and turn from OFF to ON
eight times in rapid succession
(within 10 seconds) ending in ON. After doors lock/unlock, press any
control on all transmitters (up to four). When completed, turn the
ignition to OFF. The doors will lock/unlock one last time to confirm
completion of program mode.
All transmitters must be programmed at the same time.

sounds like the key fobs have screwed up _ they could need re-setting but l would call a dealer to find out more info

on my 2010 ford escape XLT i found the keyless entry code printed on a label on the smart junction box which is inside the center console. To get to the smart junction box follow these instructions.
1. with a non-marring tool(i used a putty knike wrapped in plastic wrap), pry up the chrome trim piece around the shifter.
2. Remove the storage tray from underneath the center console armrest and leave the armrest cover open.
3. Grab the center console finish panel near the cupholders and pull straight up.
4. Pull the finish panel up and back then set it aside.
5. The smart junction box is to the right and slightly ahead of the gear shifter. There should be a label with a bar code that says FoMoCo. In the corner of this label is a 5 digit number. This is the factory code.
Hope this helps.

there should be a relay and a fuse for the locks and the windows
