What bypass module(s) are needed on a 2004 Explorer and a 2004 Envoy XUV? Can a 555U be used on the XUV? Thanks

The Exployer can use the following: Part #: 556S, 556U, or 555U.
The Envoy can use the following: Part #: 555L or 555T

I would recommend using a 555u on the Ford, alot easier and user friendly to use than the Ford cats eye. Blank keys are soo much easier to program and the ring has less of a tolerance than the eye does.

i just got a few of the KEYLESS/DATA bypasses,i haven't tried them yet,but the other stuff I've gotten great results! i hate it when people permanently bypass them by destroying a key,and hot-melting the capsule to the ignition..i go out of my way to keep the factory pats/vats/whatever they call it;working..except of course the early 90's gm's/caddies that start every once in a while,i have seen several of these..but one thing i do is put in another relay,and dis-connect my vats bypass along with the starter wire,i put this relay farther away so IF someone does try,they might not realize why the vehicle isnt starting,and hopefully give up.. and of course this disable is bypassed when remote started,or not armed..
oh and if you want an active armed alarm(no locking keys in),and dome light supervision(just a nice feature) and auto-rearm( a security related feature,tell me you have never pushed the disarm button,and found the car unlocked when you get to it..?!) it is easy to get all of these in early 90's and before cars where the dome can be used as a trigger(will address this as well) i will start a thread on this in security,my posts are generally too long already!

Where can I get a blank key from? Also, will the 555U work on the Envoy? Thanks for the help so far.

no, you need the 555L ( 555T has been discontinued ) it takes all of 5 minutes to install......

Or you could use a PLXR on the Envoy, quick and easy, or PL2004, or GMDAA Or GMDB8,
