I didn't figure it out, I just posted it in a different format...but a few minutes with Excel and anyone can produce a string that covers all of the possible combinations.

 

How is this pattern optimized?

 

until this past weekend i never locked it as the door locks didnt work

 

You can't really optimize a sequential series of numbers. It's just all of the possible 5 key combinations you could use to find the entry code(s). The only "optimization" that is done is that it removes the extra 5 character combinations.

If you look at the keypad, it's not 10 digits to choose from, only 5 (5 buttons)...so "00001 is the same as "99991" (hence why the sequence starts with "99991" instead of "00001". This way you don't enter any sequences twice.

 

The keyless system has a first-in-first-out 5 digit buffer which leaves room for optimization.

For instance, the following sequence is pointless
11111 11113
Because it could be replaced by
111113

Also, if we continue the sequence
111113111151111....
there is no need to repeat the following combinations
11131 11311 13111 31111
11151 11511 15111 51111

So there is a series which minimizes the number of button presses by exploiting the buffer. I believe the published series may have the solution. I'm just wondering if there is an easy algorithm to solve it. I'm too lazy to go get paper

 

The string already does that to a point. That's why the instructions for newer models (2002 or newer) that once the keypad locks up, you have to go back 4 numbers after resetting the keypad. You could try to optimize it more, but you start to hit the law of diminishing returns.

 

Do you have to relabel the key pad so it is 0.1.2.3.4 for this to work.
Ive seen it on here but the code list has 5.6.7.8.9s in it?
Any help please
309.235.2028.
Thanks.

 

...you didn't actually look at the string did you? The first one reads:
"99991 11113 11115 11117 11119 11133 11135 11137"

Lots of 5's, 7's and 9's in it. . What you won't see are any even numbers.

Press the appropriate key for the code we give you just like they are labeled...you are over-thinking it.

 

Does the keypad work if the "Theft" light on the dash is blinking? I recently bought an '01, the previous owner didn't have the keypad code, and the Theft light will blink for a number of minutes after the engine starts.


thanks,

Not sure...this is from the owner manual:

SECURILOCK
PASSIVE ANTI-THEFT SYSTEM
The SecuriLock passive anti-theft system provides an advanced level of vehicle theft protection. Your vehicle’s engine can only be started with the two special SecuriLock electronically coded keys provided with your vehicle. Each time you start your vehicle, the SecuriLock key is read by the SecuriLock passive anti-theft system. If the SecuriLock key identification code matches the code stored in the SecuriLock anti-theft system, the vehicle’s engine is allowed to start. If the SecuriLock key identification code does not match the code stored in the system or if a SecuriLock key is not detected (vehicle theft situation), the vehicle’s engine will not operate.

If there is any potential SecuriLock anti-theft problem with your vehicle, insure ALL SecuriLock keys for that vehicle are brought to the dealership, to aid in troubleshooting.

The SecuriLock passive anti-theft system is not compatible with aftermarket remote start systems. Use of these systems may result in vehicle starting problems and a loss of security protection. Large metallic objects, a second key or electronic devices used to purchase gasoline or similar items on the same key ring as the PATS ignition key may cause vehicle starting problems. If present, you need to keep these objects from touching the PATS ignition key while starting the engine. These objects cannot damage the PATS ignition key, but can cause a momentary problem if they are too close to the key during engine start. If a problem occurs, turn the ignition OFF and restart the engine with all other objects on the key ring held away from the ignition key. Check to make sure the encoded ignition key is an approved Ford encoded ignition key.

Spare SecuriLock keys can be purchased from your dealership and programmed to your SecuriLock passive anti-theft system. Refer to Programming spare SecuriLock keys for more information.

If one or both of your SecuriLock keys are lost or stolen and you want to ensure the lost or stolen key will not operate your vehicle, bring your vehicle and all available SecuriLock keys to your dealership for reinitialization.

Theft indicator
The theft indicator on the instrument cluster will operate as follows:
• When the ignition is OFF, the theft indicator will flash briefly every two seconds to indicate the SecuriLock system is protecting your vehicle.
• When the ignition is turned to ON or START, the theft indicator will light for three seconds and then go out. If the theft indicator stays on for an extended period of time or flashes rapidly, have the system serviced by your dealership or a qualified technician.

Since the theft light text is right with the SecuriLock text, I'm wondering if you've got an issue with a key or the SecuriLock sensor?

 

Gonna grab a couple summer shandys, head out in the shop with the laptop and find my code to shut off the auto locks. lol

 

Does the first (digit) button input before the keypad lights up count towards the code?

 

And do you wait for the light to go out between each code (5 digit) input? If you mess up on the third number and stop and wait for the keypad light to go out does it reset and "ready" for a new code?

 

I gave up and just looked under the dash. Mirror, flash light, 2 minutes and I had the code.

 

still havent tried to get mine. it hard to read and type.
