OK tackled this tonight and here are the details:
So I got the Essex KE-1601 for around 200.00 from -
Keypad Keyless Entry: A1 Electric Online Store
I also got a module called a data bus door lock interface and transponder bypass. What this does is takes the negative output from the keypad and send a signal to the cars computer to lock or unlock the doors. At the same time it turns off the factory alarm and does all the convenience feature just like your remote. This particular product is also used when installing a remote started kit but I did not use any of those features so I really only had to hook up 5 wires just to make it control the door locks. This was $66.00 from -
Vehicle Specific Auto Alarms & Remote Car Starters - CHDL7-PK2 Chrysler/Dodge
First location of the keypad - I would have liked to had it above the door handle (just for ease of use) and there was room to squeeze it in behind the door but the metal on the top of the door handle has a little more of a curve than the metal below the handle so I decided to play it safe and go below as I do not know how the keypad will sit within a curved surface.
SO I tapped off the area and located my template (just eyeballed level) so the overlay sticker sat about 1/4 inch below the door handle concave in the door.
Then I gave each of the 7 holes a good center punch then drilled them all out with a 3/16 inch drill bit:
Then I taped up the outer two holes to make sure I did not Drill them out to the larger diameter. (no recovering from that mistake)
I then used a 9/16 Inch drill bit to make the 5 center holes larger. You could also use a step bit for this.
Carefully deburred the metal inside and outside the door and this is what I had:
And this is the keypad mounted up (held in place by two phillips screws) without the overlay:
And here is the overlay stuck on
And from a distance:
Then I wired up the Module and keypad:
I got power and ground right in the door off one of the harnesses. Then had to run one wire into the interior of the vehicle for the data bus connection. The rubber boot that links the door to the car pops out with a little persuasion and you are able to take the boot off so you can fish the wire through next to the existing connector that's is already there. The hardest part was connecting the data bus wire to an orange and white wire that is near the ignition switch. My diagram said it was accessible just by taking off the piece around the ignition but I found they have moved it to the right side of the ignition switch as opposed to on top like my diagram showed. So I had to take the radio out to get to the area to connect the data wire. But the entire installation only required about 6 connections:
12 volt continuous Power for keypad and bypass module (connected to same vehicle wire in door)
Ground for keypad and bypass module (connected to same vehicle wire in door)
Door lock (Keypad to module connection)
Door unlock (Keypad to module connection)
Data Bus wire (up near ignition switch)
Keypad programing button (single wire connection with ground joining the other grounds)
After all the hook ups were made I programmed my code into the keypad (easy) and just turned on the key to program the bypass module (no programming needed). Worked like a charm.
Took about 6 hours as finding the wire near the ignition was a stumbling block.
If I missed anything, I bet I did, ask away be glad to give details best I can.
HOLY CRAP. You are a very brave soul!!! I would never have been able to drill into my car like that!!!
