Proximity door locks retrofit on Wrangler/Gladiator, someone figured it out (DIY writeup)

[Jimmy07]

I take it under advisement.. order placed
my plan is to connect up to the one on the passenger side and move it back till it picks up the FOB when I am at the tailgate. See if everything else still functions. If something isn’t working I’ll try with the one from the center rear.

You could also just try using the dedicated antenna 5 circuits on the rf hub. They are pin 8 for the signal, and pin 20 for the return on the C2 connector on the hub. Then enable AP5 as smart switch, and it should wake up those circuits on the hub.

I have all the antennas enabled through the JScan app. But no luck from the tailgate with the fob but if my daughter stands next to the cab I can unlock and lock with the handle while I am standing at the tailgate. Works about 1/2 way up inside the bed.

If you leave the fob in the Jeep, lock the doors from the inside lock switch with the door open, as soon as you close the door, they should automatically unlock. If yours is not doing this, then there’s something wrong with the fobik safe feature of the BCM.

Are you sure?
Even for a 2021?
Do I need to mention it to the dealer?

Yes, this is the case for every FCA vehicle equipped with at least push button start. If you added passive entry, the dealer will be no help, as they’ll just blame it on how you added the system.
Couple possible reasons fobik safe wouldn’t work- if you only added one door handle, and enabled both left and right smart switches, there’ll be faults in the rf hub that might possibly disable fobik safe. It appears Jscan is missing a setting that is different between a passive entry gladiator and non passive entry gladiator. When I compare the BCM logs between the two, these are all the settings differences:
VehConfig 3-passive entry present- yes
Wireless-AP1 left front- smart switch
Wireless-AP2 right front- smart switch
CustSetMenu 1-Passive Entry CSM Present- yes
Wireless-tip start present- yes- on a non passive entry gladiator, this setting is set to “no”, and there’s no way for Jscan to set it to “yes”.
There is also no way for Jscan to read the BCM system ID to see exactly what other bits it might be changing in the BCM when you change target settings with it.
We’d have to see if anyone else that added passive entry could see if they lost the fobik safe feature.

Yes, you need to talk to a dealer.

FOB in cup holder, push lock button on inside door panel, watch the lock click to lock, close the door and stand back -
horn honks three times, headlights flash three times, doors unlock.
Open door, take out fob, lock and it works normally.

I need to check my wife's GC as she said it simply didn't lock - I'll try hers again and check her settings on lock/unlock.

https://www.mopar.com/en-us/care/dy...IK-Safe only executes in,while a door is ajar.

FOBIK-Safe only executes in vehicles with Passive Entry. There are three situations that trigger a FOBIK-Safe search in any Passive Entry vehicle:

1. A lock request is made by a valid Passive Entry RKE transmitter while a door is ajar.
2. A lock request is made by the Passive Entry door handle while a door is ajar.
3. A lock request is made by the door panel switch while the door is ajar.

When any of these situations occur, after all ajar doors are shut, the FOBIK-Safe search will be executed. If it finds a Passive Entry RKE transmitter inside the car, and it does not find any Passive Entry RKE transmitters outside the car, then the car will unlock and alert the customer.

NOTE: The vehicle will only unlock the doors when a valid Passive Entry RKE transmitter is detected inside the vehicle, and no valid Passive Entry RKE transmitter is detected outside the vehicle. The vehicle will not unlock the doors when any of the following conditions are met:

• The doors are manually locked using the door lock knobs.
• There is a valid Passive Entry RKE transmitter outside the vehicle and within 5 ft (1.5 m) of either Passive Entry door handle.
• Three attempts are made to lock the doors using the door panel switch and then the doors close.

I’ve made no modifications to the locking system...

I believe I had the other fob in my pocket. I’ll try again with the second fob away from the Jeep.
Once again, I haven’t yet installed the Passive Entry stuff.

I don't have any passive entry stuff (yet), and my JT prevents me from locking the fob in the vehicle exactly as described above. It beeps and flashes and the doors unlock again. Passive entry is not a requirement for this. At least it isn't for me.

Hey guys....a Jeep mechanic told me that he thinks my overland already has the wire harness installed even though my JT is not equipped with the feature.

does anyone know if certain trim levels have the correct harness already?

No FCA vehicle will ever have the door handle connector for a proximity handle populated in the harness without having the feature.

Like others have said, I don't think it will have the harness in the door. The only way to be sure is pull the panel and look. It should have the wires up to the door connector in the kick panel so all you would need is the door harness, the handle, the cap and some programming.

Yeah, like the trailer controller needs a flash or like the other harness shown in the instructions will fix the issues, and a host of other things they are generally wrong about,.
No, it won't be there. The proof is in the parts lists.
There are harnesses for Jeeps with passive entry and for those without. If they all had it, there would be one part number each for any Overland.
People on this forum with Overland and other trims have swapped out the harness to get the wires needed, supporting the "no, it's not already there" thinking.
The electronics otherwise are there -but not the wiring harness or the handle or caps.

Your mechanic may be thinking of the "antenna" - that part is already there if you have electric locks - remote entry.

I WISH the wiring was already there - I'd be done already and have passive entry.

He is a VERY knowledgeable guy but yea....prolly wrong.

how would I know for sure?

You know for sure because other Overland owners have been through this.
You know from the experience of those who have done it - dealers don't do this. In fact, go to most dealer shops and they'll say it can't be done.
Otherwise, take your door harness loose and look for the wires that feed the proximity lock system door handles. Someone here can tell which wires are in the harnesses you need to but that are not in your truck now.
You do not have those wires. Look back through this whole thread and find those who own overlands, such as myself, who have bought the necessary wiring.
