an immobilizer bypass

HI all,

 I am installing a remote start on my 2001 ford ranger, it has factory keyless entry and antitheft.  I installed an avistart 4113.  I went with a super simple setup not using the parking lights, horn, factory arm and disarm etc.  Pretty much stricly to start the truck and run the heat/ac.  the remote start is working fine, I am having a problem with the bypass.  I am using the directed 555p, now the only thing I see that may be an issue is I haven't had a spare key in over 6 years ( i have no idea where it went) and the directions say to use two keys to setup the bypass.  When I activate the remote start the led on the bypass flickers on for a split second then it comes on solid for a few seconds, but the starter never cranks, and the theft light flashes rapidly.  I have gone over the wiring and don't see any issues.  Just wondering if not having two keys is my issue and is there any way around it without buying a new costly key.  Any help would be really appreciated.

    Thanks,

         Derek

hi,
you need two keys to program the bypass. most Ford products require two master keys to program any additional keys...and bypasses since they would be considered keys.

Well if you want to make it work with only one key. there is a way. Remove the chip from the key and mount it near the transponder ring. Also disconnect your bypass since you will not need it. You could also cut some steel keys and mount the whole key near the transponder ring. You will be able to start the car with steel keys since your anti theft will be permently bypassed. This is not the professional way or the way I would do a customers car but it will work and I have done it before.

Thanks for the info.  I installed a system on my honda pilot and didn't need two keys, so i was suprized to see this one did.  Oh well I guess i'll be having to get anothe key made, not real keen on the idea of removing the chip and permanately bypassing the immobilizer, still need a little security.

Is there a starter cut or provision for one on the 4113?
If so that's the way to go with the chip removed. Been doing that over here on UK Fords but then our alarms have 2 circuit immobilisers and we never had the by-passes till recently. Done that on my Mits as well.

Howard: Unfortunately not. The 4113 is only a 1-button starter with door unlock.

tkmech21: The "Two Keys Requirement" is specific to Chryslers, Mitsubishis, and later model Fords and Mazdas (some models starting in 2000, and virtually all since 2004).

These vehicles will not go into "Learn" mode to accept a new key or a bypass unless one of two things happens:

1. The ignition is turned on and off in a specific sequence, with the car seeing 2 unique transponder signals that it already accepts.

2. A dealer scan tool is used.

Good point Krazy man, I gave a way my not having met these systems yet, I think the similar 5301 is now available over here but no chance to play with one yet.
I know with Fords and Mazdas that when I chip them I have to do ALL the keys.

Not sure of the price but there is a way to get a working bypass module with just one working key.  Contact an iDatalink authorized dealer.  They have a product / process called Klon that will produce a working ADS bypass module with just one key.

Soldering is fun!

I just ordered two keys from ebay, so when I get them I'll have to have them cut and programed.  If they Clone my key that I have now won't that be the same as trying to use the same key twice?  Or can they set up the new key with different "passcode" or whatever you want to call it.

The new keys will be fine.  Yes, a clone key gives the same transponder code as one that is already programmed to the car and is the same as using the same key twice and won't allow you to enter into "Learn" mode to add a new one.  Having only one working transponder key is not a good idea, especially on a Toyota.

I got the keys and got them cut and programmed, when trying to leard the bypass to the truck, the theft light flashes like it is not taking the code from the bypass.  I did as the instructions say, put a key in turn it on wait till theft light goes out, pull key and insert the other turn it on wait till theft light goes out, pull key and initiate the remote start by key fob, when I initiat the remote start the theft light just flahes as the remote start goes through its process, but it never turns over the starter.  Any help is appreciated, This system has proven tougher than my honda install.

You are using the 555P bypass?

The 555P is for PATS equipped vehicles. According to what I just read your truck is Securilock, not PATS. If your truck was a 2000 the 555P would work but since yours is 2001 it will not. You need a different bypass. The DEI 1100F can be had for around $15 and works perfectly.

Ditto on that...IIRC from the Bypasskit technical info I've read, Ford actually switched the Ranger and Explorer from PATS to Securilock on July 24, 2000, so there are apparently some early 2001 models of either one which still used PATS. I've yet to ever see one, however.

If your keys look like this (the shape, not the logo), the truck's got PATS:



If they look like this, it's got Securilock:



As mentioned by the other posters, if you've got Securilock you'll need to use a different bypass - the 1100F or PKFM would work fine.
