When I go hunting in larger parties I leave a second key locked in the truck so whoever gets done with their hike first can get in cool off and drive down around the mountain to pick up the rest of us. So adding another code that everyone can remember is great. I can't remember the factory code so I added my own as well.

 

Great info here!

 

Although there are 10 numbers on the pads, there are really only 5 buttons. For example, selecting a number "7" is no different than selecting a number "8". Therefore, the possible number of button combinations is 5 to the fifth power (5^5 in excel) or 5 x 5 x 5 x 5 x 5 = 3125.

If there were actually 10 buttons there would be 10,000,000,000 (10^10) possible combinations.

If it was truly digital and all 10 digits could be used in each of the 5 "positions" the number of possible combinations is 10^5 or 100,000.

Relate to a 4 digit PIN for a bank card, etc. where there are 10^4 or 10,000 possible combinations.

 

Even with just 3125, that is a long time to stand at the door furiously punching numbers in sequence hoping to get lucky. At a quick 2 seconds per attempt, that could be almost 2 hours of continuously punching in codes as fast as you can to crack it via brute-force. Doable, but most scumbags are not willing to hang around at a single car for that long -- attracts a lot of attention. On that thought though, does anyone know if the keypad (or the lock receiver) gives itself a timeout after XX failed combination attempts?

 

From the Owner's Manual, page 72:

Anti-Scan Feature

The keypad will go into an anti-scan mode if you enter the wrong code seven times (35 consecutive button presses). This mode disables the keypad for one minute and the keypad lamp will flash.

The anti-scan feature will turn off after:

• One minute of keypad inactivity.
• Pressing the unlock button on the remote control.
• Switching the ignition on.
• Unlocking the vehicle using intelligent access.

 

Totally agree with the last 2 posts. I'm not concerned about keypad security. With channel-lock pliers you can break the front driver side door lock in about 10 s.

 

According to the flat head pry marks under my passenger side door handle, thieves dont care about the door code either.


The master code is also on the PCM under the passenger kick panel/ plastic panel on the floor of the right side of the passenger foot well. Plenty of Youtube videos on this.

 

You meant BCM right? The PCM is on the cowl under the hood.

 

lol Yeah whatever is the one in there.


Also, how I have been able to remember the door codes, is to add them as a contact in my phone. My Truck Code 01234. Dads Truck Code 43210. Etc.

 

yeah it's a serious problem. My ex wife has gotten into my vehicle taken Checks stolen watches and forged my signature on checks. I changed the code when I saw she was commiting fraud but because we weren't officially divorced yet there was nothing my bank could do I had to eat the fraud even with a clearly forged signature in my checks written to her father. I changed the code to protect myself as my.bank said we can't issue another bank account if you give away your personal information so easily. Then she's in my truck again stealing my watches and new checks and opening my stuff and commiting fraud against me and how am I to run a business with no bank account and pay for my children and all the bills and the lawyers I need to pay more to get rid of this crazy women for once and for all. Ford ****ed us all over this way she read the code in my glove box in the manual years ago and clearly I'm dumb and get robbed again even though I changed it for good reason. Little did I know it wasn't really a new code to get. She just used the original one. What a joke.
