I need some help with an alarm installation. My daughter has a 2002 Protégé ES. Unbeknownst to me, she decided to have an Alpine SEC-105S alarm installed. As you know, the factory keyless entry system provides for depressing the unlock button once for the drivers door and a second time for all doors. That is now the problem. What happens now is that when she presses the unlock button on the Alpine, the drivers door unlocks and about a half a second later, all doors unlock which is unacceptable to her. The installer told her that the pulse for “door unlock” from the Alpine is 1 second, which he says, is too long to be able to do what the factory keyless entry system does. This doesn’t sound right to me as the Alpine is a 3-channel alarm so I think he just didn’t wire it correctly. In Alpine’s infinite wisdom, one doesn’t get an installation manual with the alarm so I am not sure about the wiring but I know where the control unit is and it looks like the installer by-passed the keyless entry module entirely which may be the problem.

If anyone can offer some suggestions, it would be greatly appreciated. In doing a search, all I seem to find are people that want to disable the “two-press all door unlock” and not enable it.

Thanks in advance for any replies.

Alpines site is buggin out right now, but if you go to www.alpine1.com, you can get manuals online. And i would tend to think that the alarm has the priority capability, the installer sounds lazy...or uneducated on the subject.

also, if you search this "electronics" forum, you'll find all the info needed for the installation.

Unfortunately, the Alpine site has been like this for a few days but unless something has changed user manuals are available but not installation manuals. It also turns out that the newer Alpines have the wiring diagram embossed on the case but I have to take the alarm out of the car to see it. I totally agree with your observations and yes, the alarm has a priority capability built-in. In your experience would aftermarket alarms take advantage of the keyless entry system or bypass it entirely? Secondly, I recall there is a "driver door" and "all door" output on the keyless entry system. Can you confirm or deny?

I'll keep searching. If you don't know, no one probably does. <sigh>

Without seeing the OEM wiring diagram for the keyless, i couldn't tell you for sure, but i do suspect you can tap the wires without the addition of relays. If your sure the Alpine has the priority option, then it's entirely possible to have it work as such with the addition of relays, if the factory keyless is not accessible or wired in such a way that it's not possible to tap onto.

There are 2 types of alarms for cars with factory keyless, the regular type that comes with remotes etc...and, yes, this type usually installs separately from the factory keyless, as it will still work as usual, but have no control over the alarm. and then there is an upgrade style, that retains the use of the keyless remotes, therefore the keyless goes unchanged as far as functions, just gets added onto.

I have been able to get install manuals from that site before...? but it does look a little different now...???

Hey, thanks for the help. I have been following this thread http://www.protegeclub.com/forum/sho...&threadid=9406 and this thread http://www.protegeclub.com/forum/sho...threadid=10911 which give me the instructions for the relay option. If there are separate outputs from the keyless entry system (assuming they can work without relays), this would be much easier to implement.

At least, with your help, I am on the right track. Regarding the manuals...one of the reasons I would never use Alpine alarms, finding the installation manuals is a royal PITA.

Thanks again.

Hey ManiacDad,
As Darryl was saying, there's 2 kinds of alarms... the "Add-on" which makes use of the existing keyless entry, and the full-on alarm, which replaces the OEM keyless entry & transmitter w/ it's own. I suspect you got the latter. If you received a new transmitter w/ the alarm, you most likely got a full-on alarm. And since the installer was talking about pulsed-output times, that suggests the type that replaces the OEM keyless entry. I just installed a Add-on which was crap, removed it all, and then added a full-on alarm which was better. So trial-by-fire, I learned the in's and out's of the keyless entry system.

If the alarm has driver's door and other door outputs, then it's definitely capable of driver's door priority unlock. The installer just got lazy and lied to you about the reason why (the time-length of the pulse output has nothing to do w/ driver's door priority).. or (benefit of doubt), he/she didn't understand it. The trick is tapping into the right wires. Unless all of the relays are built into the module, you'll need to add relays. Looks like you found Darryl's & my posts about this wiring. But I'd go back to the installer and talk to the manager now that you're informed (more informed than they are). It's ok if you have to take the wiring directions to them, but they should complete this installation correctly unless you signed some agreement waiving driver's door priority.

When you do your own install, you're not a "dealer-installer" so you can't qualify for the insurance the alarm companies provide. It's BS that clowns like this can do a hack job and this supposed "dealer-know-how" is what makes the installation worthy of insuring.

Good luck,
Don Caballero

Thanks Don. I appreciate your advice. I looked at the updated posts this morning and it is very clear to me. The Alpine is a stand-alone alarm (with its own remotes) and seems to have a lot of capability. You are right...the installer has some serious "problems." The car is going back today so I guess I have to be the teacher. Jeez.

Thanks again for your reply.
