I'm using a design tech bypass module. Do I need to cut the key open to mount the transponder in the bypass box or can I keep the key intact?(this is the GM small headed key not like the Ford key ) been trying to reposition the key under the wire loop field but no good. want to verify if I'm going down the rite path before I butcher this key. Is there another option? thank you, Mark

no dont butcher the key , make sure the antenna ring is in the right position that is more likely your problem. are you using a module from ie: dei, aamp or is it home made???

You shouldn't have to cut the key open for the transponder signal to be picked up. Make sure the other details of the bypass are correct, i.e. wires going to the correct outputs from remote start, transponder ring securely around ignition switch, etc.

This is the bypass mod I use. https://www.designtech-intl.com/merchant.ihtml?pid=114&lastcatid=3&step=4 It is the type that has a wire that needs to be looped around the ign switch two turns, then is fed back to the module,that is done. and the key sits inside the module. I use these with the Ford Pats system with no problem. But this GM Passkey III does not have the same type of large key head, it is smaller, and before i butcher the key I want to see if anyone else does it this way or another? PS: I can place the key in the ingition switch and the car starts just fine by remote. also, the remote start unit does close the relays in the bypass module.verified all that. the module does energise.

the only other thing is the antenna ring is not in the right place behind the dash

I never liked these universal type bypass modules that has that key cylinder ring. The ring is always over sized and the module that the key goes into is also too big for some keys ( not all keys are FORD keys ). The biggest problem will be placing the ring close enough to the key cylinder to introduce the signal to the Passkey III module.

We have two units that are KEYLESS for your car ( GTP and non-GTP as well ). Simple installation and safer than having a key in the car. Please email me if more information is required.

I dont want to buy aditional parts! I want to use what I already have. If anyone has done this let me know if not dont try to sell me stuff.

Not trying to sell you stuff, rather give you other choices and options available. Here's what you do.... get rid of the DT piece and use this diagram to bypass the Passkey system with a spare key. It will work all the time that the RS unit engages the starter, but will be off otherwise and the small gauge wire will wrap tighter around the cylinder than that big @$$ DT ring will so it will induce the signal alot easier: https://www.velocitymotorsport.com/install_notes/Ford_PATS_bypass.htm I know this is the diagram for a FORD, but it's a universal diagram that will work with any transponder key. Hope this helps and sorry if I offended you by offering you another product. ------------- Jeff

Jeff, no prob, sorry if I seemed off color. didn't mean it that way. anyway- I have the GM small key head, odds are I'll break the transponder getting it out(dont realy want to chance it). I dont have the large ring for the key cylinder, I have the single strand wire. I've done this relay trick you described before many times with the ford transponder. I think I have my problem narowed down- the key cylinder wraped wire from the bypass mod is to close to the metal of the key cylinder. going to form it first(flat circle) then glue it to the plastic passlockIII oem black housing(3 turns also not just 2.). will let you guys know how it turns out . thisafternoons job. thanks for your help. hope I can return the fav soon.

making the loop first and placing it worked great! its flat and can easily be stuffed between the key cilinder and plastic steering colom cover, WITHOUT removing the key cylinder(tumblers). best and fastest way I've done one yet. thank you all. hope this can help someone in the future! Mark
