Anyways u have to buy one from ebay and possibly pay like 80 bucks to have them program it.
Say u had to factory keys for the truck you could then program a 3rd you self but if you only have one you cant do a second
Here is how you do it if you have the correct 2 original keys
Two working PATS
keys for that vehicle;
key or keys cut to match the working keys.
The Ford Passive Anti-Theft System, also known as PATS
or Securilock, uses a special transponder key as a theft deterrent. Several years of Rangers through 2004 use Securilock. A PATS
key, recognized by the truck's PATS
transceiver, is required to enable starter operation on a PATS
If you need extra keys for your Securilock system, you could let the dealer handle it for you. This is quite expensive and usually runs $60~100 parts and labor. Or you can purchase the key and easily program the tranceiver yourself. Uncut genuine Ford PATS
keys usually run about $15 + S&H on eBay. I got mine at the local Ford dealer for $20 and they were nice enough to cut it for free.
So, you already have the two original PATS
keys that were delivered with your new truck. Why should you buy a third key? Because you need two working PATS
in order to program the transceiver to recognize any additional keys. If you haven’t made more and you lose one of your two originals, you are toast. The only way to get a replacement then is to go to the dealer or a locksmith. The dealer has the capability to make replacement keys without having two originals but that will usually cost well over $100.
I bought my third key as a sort of insurance. For a $20 investment, I can always make more as long as I have two available.
Be sure to get the correct PATS
key for your year Securilock. You can have the teeth cut to match one of your original PATS
keys’ pattern at the Ford dealer, a locksmith or at most hardware stores.
Have all three PATS
keys available – two working keys and your new one, ready to program for. The programming procedure involves inserting a key into the ignition switch, turning the switch to the “ON” position, then turning the switch “OFF” and removing the key. This is done to each of the three keys and must be done within the allowable time limits. Keep in mind that you don't need to turn the key to the “START” or “ACC” positions during programming. Use only the “OFF” and “ON” ignition switch positions.
The following is the procedure to program for a new Securilock key:
1) Insert one of your two working keys into the ignition switch and turn the ignition “ON”, wait 5 seconds and turn it “OFF”. Remove the key immediately.
2) Insert the next working key into the ignition switch within 20 seconds. Quickly turn the ignition “ON”, wait 5 seconds and turn it “OFF”. Remove the key immediately.
3) Now insert the new PATS
key within 20 seconds. Turn the ignition “ON”, wait 5 seconds and turn it “OFF”. Your new PATS
key should now be recognized by the transceiver.
4) Use the new key to turn the ignition switch to the “START” position. If programming was successful, the engine will start as usual. Take a moment to congratulate yourself on saving a chunk of change.
If unsuccessful, repeat the above procedure, paying close attention to staying within the allowable time limits:
Keys must remain switched to the “ON” position for between 1 and 10 seconds:
There is a 20 second time limit between successive keys.
[NOTE: If you have more than one additional new key, you can repeat step 3 above for each of the new keys up to a total of 8 keys per vehicle]
