Is it possible to change (or have the dealer change) the permanent access code for a keyless entry system? If so, how might this affect the Ford roadside assistance plan? They provide a space for the code on their wallet cards.

My 12-year old genius has found and memorized the permanent code. I don't want him to have on-a-whim access to my truck. Hopefully the code can be changed.

 

The access code from ford sticks forever. You can change it to what you want, but the base will always be there.

 

I know hindsight is always 20/20, but my approach is to make a custom code and give that one out, and keep the permanent one a secret.

 

Agreed. Best I can do now is beat him to the punch with the remote unlock, and hope he forgets the number with disuse.

 

Serious reply here,

How about you tell him that if he uses it without your consent that you will slap the **** out of him. Tell him that it's your truck and that if you catch him in it, it's on. Or Tell him to stop using that code bc "it's a ford dealership code that sends all kind of crazy alerts each time it's used and you have to start paying a fee effective immediately each time it's punched in".

 

I appreciate your suggestions. The first one isn't my style. The second is quite good, actually. Thanks.

 

If you absolutely have to keep him out, you are going to have to make a rule, and enforce it with punishment if broken. You know, the kind of boundary setting you should have been doing for the last 12 years. It's not to late OP. Kids without boundaries grow into adults without boundaries and that is never a good thing.

I've asked if the keyless entry system could be programmed with a new default code. Any suggestions?

 

The factory code can only be changed by replacing the body control module, very expensive.

And the first person gave you the answer. No.
