Hi! I just recently losy one set of keys for my Magnum and will need to go to the dealer for a new one. Im looking at about $200 for one damn key!:cry: Anyways I am running a hacked PCM from B&G, should i be worried? I mean they dont have to flash the PCM or anything right? I know I have to take the car though for the programming procedure. I just dont want to deal with the slight hassle of changing PCMs....Im lazy! LOL!!:ronlove:
Um, I don't know.... It's the security module in the pcm programming that's involved. I believe there is a "manual" procedure for doing it with the car or I think I remember they can do it with a starscan? If they hook a starscan up to the car it may flag it as a non-standard pcm and even if it doesn't they may just check for updates as standard procedure and flash it for you if there are any? Get your lazy butt out there and swap the PCMs.
I'm thinking that is probably the best approach...especially if there is a warranty that you would like to keep intact. Better safe than sorry. If you don't want the hassles, you could call around to a few local locksmiths, find one that has the ability to program the key, then you don't need to worry about the dealer. At $200 for a dealer key, a locksmith shouldn't be much over that, if not under. Just an idea...:dunno2:
hmmm I do not remember them hooking my car to StarScan when my dealer got me the new key and alarm fob? I do remeber them writing down the VIN, and then using a computer in the key storage room to code... But then again, I could be missing a step. lol
That what I was told too but I wanted to check. I will call them again to ask more precisely how the procedure is....
Maybe no StarScan then. Yes the key has to be programmed but I think the PCM has to know about the key too. You can have a max of 7? keys active with the car at one time. something like that so the PCM knows the key too (at least it stores the key ID maybe?). The "manual" way of adding a spare key requires 2 already programmed keys and then you can do the 3rd and subsequent ones using the car up to some max. Haha, you figured you could save the hassle of swapping your PCMs, now you're going to have a SRT/C laundry list to take in with you... 1) *exactly* how does it work? 2) Des each key fob have a unique ID? 3) What info gets swapped when you program a key to the car? 4) Does the PCM store information about each key fob programmed to it? 5) Is there a maximum? like if you need a bunch of spares and you keep losing one of them and replacing it, at some point do you have to start over and have them all reprogrammed? thanks man
I believe the max is eight keys...IDK for sure with the Chryslers, as we don't do much work with cars here on campus...but we have a ford truck that has reached it's programing limit. We can cut all the keys we want for it, but can't program them, 'cause it won't take. Maybe with the computer you can reset the "log" and start over, but if you use the self programming mode. (2keys) and keep loosing the keys you will max out. EDIT: As for #4...the CPU or security mechanism, has to keep track of some kind of info on the keys, otherwise how would it know when the maximum was reached.
