Adding remote to base Millenia (95)

[millyowner]

It sounds like I may have had the thing working all along and I just never got round to replacing the battery in the remote. I hope that's it. Otherwise, I've spent too much on a not so effective paperweight.

Yeah I'm not sure what the deal is with the trunk. It has a 4-pin relay that's no different between keyless/base models. The door lock relay seems to have lots more active pins on keyless entry cars though. My original relay was black and the one I replaced it with is green with a slightly different part number.

Ordinarily, when pressing the unlock button once. The driver's side door should unlock only. A second press, and the other three doors then unlock. Without the door relay, I'm thinking it unlocks all the doors simultaneously (as it does during the diagnostic for me with the original relay).

Alright, the batteries in my remote have tested good, but it still won't recognize me pressing any buttons during the program procedure. Perhaps my remote is dead. I opened it up and discovered some green goo on the button contacts. I cleaned it all up while I was in there and damaged the soldering on the B+ battery connector, so I'll have to see if resoldering it will make it work now. I'm not buying another 1995 model remote...I'll buy a new keyless unit and remote from a newer one for much less if I have to try again.

As for the trunk release not working...perhaps non-keyless equipped cars have a different CPU part #? Otherwise, I'm not sure.

Thats interesting on the door relay. I'll have to look at that again. Maybe thats why when I go to unlock the door it seems like I have to hold down unlock or hit unlock twice for it to open. Not like lock where its just a quick tap. On the programing procedure are you getting up to the one beep signaling you to press the remote buttons to program each one?

good info on the green door relay. I went out and swapped my black relay for the green door relay after reading your post. Both seem to have the same numbers "BCIE 67830" but only different housing color. Anyways after the swap remote now unlocks Driver door only with a quick tap, and all doors when held down. So guess I needed that relay after all. Now for the trunk, Is the relay next to the door relay the trunk relay? The relay that says H300.

Yeah, it beeps once and I have 15 seconds to press a remote button twice. After pressing the buttons on the remote two dozen times, after 15 seconds, I get 4 beeps saying it's too late. I've tried it with two keyless entry units with the same result. I'm about to leave for work and I'm taking my soldering iron with me. Hopefully, I broke and fixed the remote by cleaning it.

Yep, H300 is the trunk release relay. It seems to be a standard 4-pin type and isn't actuated any differently than when the trunk release button is pressed. The signal from the release button --> CPU --> release relay gets passed but keyless entry unit --> CPU --> release relay is not accomplished.The trunk release is the only part of the diagnostic it doesn't pass now. It still dings once after the diagnostic indicating that everything with the system is OK though.

Well, today checked that relay I suspected to be the trunk release relay. "H300" unpluged it and tried to unlock the trunk with the release button on the driver door and it still popped open. So, either the door release button doesn't use a relay or "H300" isn't the trunk relay. As for your remote did you fix it and try it again. Also are your receiver and remote matching. like mine are transmitter: KPU41048 receiver: KPU41049 for the 96-00 models.

Well I guess I need to look a little deeper on the relay issue.

I fixed the cold soldering joints and tried programming it again. Nothing.

The two receiver units from 1995 models I have both say KPU41049 on them too (?). As for the remote, it says KPU41012, but that's just its little black plastic case. It's possible the transmitter has guts from a 1996+ remote since I bought it used on eBay and have never gotten it to work. It's also possible the receiver units I have aren't original. The remote may have even been broken from the start, though it wasn't cheap and the seller said it was "tested" and all they sold were used keyless remotes. I just don't know.

I may be wrong, but I am under the strong impression that the 1996-2000 keyless entry units say KPU41049 and the transmitters that match with that unit are the KPU41048. Well going to try and do some research on that. Not sure what year the KPU41012 transmitter is from.

[popo]

Well looked around the KPU41012 is definately the model transmiter for the 1995 model millenia, but It makes me wonder about your receivers, since they are the same as the 1996-2000 KPU41049 receiver. Did you physically remove these units from a 1995 model? Only other thing I can think of is try a remote for a (KPU41048) 1996-2000.... Well after typing this went to search the FCC ID number at this website
https://gullfoss2.fcc.gov/prod/oet/cf/eas/r...nericSearch.cfm

you only enter KPU in the first line and the numbers in the next line

anyways for your KPU 41012 remote is frequency 319.0

remote KPU 41048 is 314.5-315.5
receiver 41049 is 314.5-315.5

I think this may be the receiver you need for your remote KPU41013 frequency 319.0.
