07 escalade pke/rxt/smartstart + ak

The end goal I'm looking for is to be able to Use the PKE 2102T to unlock the car and just hop in the truck and use the Advanced keys Knob Switch Key Cap, AK-TS01, with a dummy key (no chip) to start the truck and drive off. I would still like to retain the SmartStart functionality.

I have the dball2 and smartstart already functional in RXT mode with the T-Harness.

I also have the PKE hooked up to everything but the door locks.

Hence the first issue.
Easiest way to hook up door locks?
Tried to actuate the dball2 door lock input wires with the PKE door lock output grounds and I guess the firmware turns off this functionality. Really not looking forward to 5wireing the door locks but is this the only option?

Second issue,
Using the Advanced keys Knob Switch Key Cap, AK-TS01.
I would like to give ground to the Ground While Activated/Running DBALL 2 wire with the PKE to allow me to start the car only when the PKE fob is present. The key would not start the car without PKE because the chip would not be programmed/present. I'm pretty sure I would have to bypass the keysense wire to trick the truck to think the key wasn't there in order to remote start/smart start but have it think it is there when the PKE is disarmed and active. (I haven't gotten a dummy key cut yet to test, but I'm thinking I'll run into the same firmware issue as the door locks)

I'm really trying to do this the easiest way possible, but it looks like I may have to do a full remote start install/non(RSR/RXT) install to get all the functionality I want.

Any suggestions? Ways to get custom firmware? Thanks in advance!

Am I missing any information that is needed to provide a helpful answer to my questions? Surprised that no one has posted as I thought this was a pretty unique challange. This is definitely not my first install but definitely one that I'm trying to customize to my needs. Thanks again in advance!

Did I post in wrong forum? Surprised no one has commented.

Anyone? Some nugget of insight?

Apologies that no one has replied, unfortunately my response won't be of much help. Just an explanation as to why no one has replied thus far.

You are attempting a one off task using products not most of us use. Aside from the dball obviously.

For that reason a company like DEI is not going to get into custom firmware. A couple hundred dollars if even that much they can squeeze out of you for the service does not begin to cover the couple hundred thousand dollar liability they risk if something goes wrong.

You could always reverse engineer the software yourself but obviously that is illegal and cant be discussed here.

That is all I can offer. Maybe someone will chime in with any help they can offer. Good luck and sorry we haven't been more help!

Sounds like what you want is the AK-104S Universal system. You can try to cobble something together but it's going to take a bit of trial and error to do, especially with the parts at-hand/in-mind that were never meant to be used in the manner your conceiving.

Thank you so much for both of your replies!

I assumed that custom firmware was a long shot, but I also didn't know if anyone had gotten into the code as messed around or if everyone just took what was given. I was going with the same mentality/concept as jail breaking a phone/custom firmware.

I was trying to use DEI hardware so it would work with the SmartStart I already have installed with the dball and the directed PKE as well. The dball has input wires for door locks, they just don't work on an rxt install with smartstart which is lame. Would help with a lot of customizaition.

So I put this one on the back burner for a little bit and as usually happens I thought of a cheap solution. I will leave the smart start and dball hooked up as it's own system. I then plan to use a xk01 and a 556U with the PKE.   The XK01 will take care of the door locks and status inputs for the PKE and I'll use the "Starter Kill Output"(have to invert it with a relay so I get a ground when unarmed) on the PKE to activate the 556U and I'm golden. Low tech solution for ~$40. I was stumped when I was trying to do it as an all in one solution.

   I explored some other modules but the firmware and wiring configurations it gets more complicated than it needs to be.

If I am reading correctly you may have issues with multiple data interfaces either causing loss of communication with each other, or the car. Or worse cause the cars computer to stop communicating correctly.

It will either work perfectly or leave you stranded randomly. I say good luck either way!

Since neither of the systems (DSM250 + dball2 , D2D , RXT) and (pke + xk01 + 556U, W2W) will be talking to each other there shouldn't be a loss of communication between them.

When I considered the communication with the car, I made the assumption that since the car is not programmed to accept the modules, they are just simply telling the on-board computer to execute a command or receiving a signal from the computer.   If this is the case then the only issue is if one module told the car to execute a command and the other module did something in response to that command as well as the car. I find this unlikely because you could just as easily hook a code reader up to the car and run diagnostics and perform the same functions we are asking these modules to do without any ill effects from/to the modules.

In summary however I agree it will either be a success, a total failure, or somewhere in between. Fingers crossed as I already have the modules on order! Hopefully I get some time next week to get it installed! Cheers!

I can't help but think a cheap solution for a cadillac escalade, really?

Not for me to understand I suppose. I don't get the difficulty of putting a key into the ignition and turning it if you still have to turn it even after all this non-sense.

Reason 1:
I don't have to get the key out of my pocket with passive key-less entry to get in the car while I'm holding my gym bag, laptop bag, groceries, or the million other things to get in the truck.

Reason 2:
Even better as happened a few weeks ago. I was parking at the gym. Opened the door to step out and the wind caught my drivers door. Swiftly grabbed for the door to stop it from slamming against the parked car next to me. As it turns out my keys were in my left hand and as I caught the top of the door I also jammed my key into the paint all the way through to the metal. (expletives were said!)

As for cheap, the only reason I have an Escalade is because I find the best deals/options to get what I want...

-------------
Jeffery

I still don't get it.

The Escalade (IMO) is not the best deal/option in any regard outside of buying the Cadillac emblem and having it on an SUV.

Bought my extremely low miles EXT with light damage to the front end for less than a Honda Accord. Fixed it at my own body shop for $3k and ended up saving about $10k under KBB.

Has way more options than the Avalanche that I used to own. And I like the looks.

And what's great it is really not about if you get it. It is about if I get it and want to put the effort in to achieve it. In the process I learn how to do something I didn't know how to do and I get what I want out of the endeavor. Weither or not anyone else thinks the idea has merit is of no consequence.

And besides this forum isn't about my truck as a good choice or if putting pke on it is worth doing. It is solely to help solve the problem as stated and to assist anyone after the problem is solved with the information to more easily accomplish the same task.

Pke is operational with the xk01. Now for the fun part of integrating the 556uw with it to get my end result. Cheers!

Jeffery

The pke install with the xk01 was so stinking easy I knew I was in for it when I when to put the 556UW in the truck.

556UW is installed but will not let the engine start with non-programmed key. I believe the 556UW is functional because the truck won't start with a programmed key while the 556UW is on (truck is "seeing" 2 keys). I have wired in a switch so 556UW can be disabled when use of a programmed key is required. Switch off the bypass and truck starts as normal.

I have also wired so that all remote start functions still operate with key in ignition. This is achieved by only connecting keysense once the key has been turned to the ignition on position.

Any suggestions in testing the 556UW or for achieving ignition would be greatly appreciated. I have gone back through relays to check the correct signals are being achieved and sent with my multimeter. Even tested hooking the 556uw straight to power, ground, and status to no avail.
Thanks in advance!

Even a non-programmed transponder key behaves like your original does when inserted. It communicates with the immobilizer even if it's not an authorized key i.e. it's seeing two keys.

Face-palm...Thank you catback! That makes absolute sense. Well hopefully I can break off the back of the key, assuming that is where the transponder chip is, as was my intention to use the Advance Keys knob and all will be solved.
Thanks again!

Jeffery

Removed the plastic/chip from the key and bingo started right up! Advanced keys Knob Switch Key Cap AK-TS01 is ordered so put the polishing touches on the install. Thanks so much catback!
