    One of the nicest things I did to my old 308 was add keyless entry. I found a nice Crimeguard keyless-entry only (no alarm) unit from Crutchfield, and have since bought another for girlfriend's honda.

    On the 308, I had to install actuators in each door.

    On my (to be delivered) 328, I know the passenger door has an actuator, but I don't know for sure if the passenger door has an actuator.

    I've read reports that some 328s can unlock the driver's door from the passenger side, but even on 328s that couldn't, this doesn't mean that there wasn't an actuator on the driver's door side...

    Any ideas for sure?

    Also, any ideas where the central door locking "brain" is located? I'll need to tap into it with keyless entry "brain" :).

    Michael,
    the 328 has (I believe) actuators in each door. That is, if you unlock/lock either door, the other unlocks/locks, at the same time. I don't know where the main relay or "brain" is, but I think the Crimeguard unit should be able to be tapped into it. Please keep us posted on this, as I have been looking at that unit from Crutchfield for the past year, thinking of doing the same thing....

    Dave, it is an extraordinary unit. Well designed. The controllers are an upgraded look/feel from those pictured on the Crutchfield site. I put this eystem in on my 308, then on the Honda as well. Well documented, lots of features, and very easy to use in practice. As picky as I am, I can find not one single complaint about the system or the remote controllers--it's just well engineered, and obviously is quite an evolved piece of equipment. Crutchfield, as a retailer, is much the same way--always top notch service.

    This unit has "starter kill" capability, so has an anti-theft component to it useful for insurance.

    It's $70, if I recall, and one of the nicest upgrades I had to the 308. Just think: no wear in the door locks, no stooping over (even for us short guys!) to unlock the doors, and no paint scratches around the door lock!

    So, you're saying on your 328, the driver's door will unlock if you unlock the passenger door? What then, is the serial # of your car?

    On the 308 with power locks you unlocking the drivers door will unlock the pass. door. Unlocking the pass. door just unlocks the pass. door.

    OK. So my 328 is #73651. Re: 308s, yeah, I was pretty sure the driver's door lock would never be a "slave" to the passenger.

    But, on Dave's car, if I've understood correctly, the driver's door lock IS a slave to the passenger, and the passenger door lock a slave to the driver's, so that they're always in sync. If this is a case, then there is an actuator in both.

    In the 308s with power door locks, it sounds like there may only be an actuator in the passenger's door, which can be verified by getting behind the door panels.

    My '89 328 (78941) has an actuator in each door. Unlocking or locking either door causes the same action to occur on the other one. This is true whether using the Clifford alarm keyfob remote, or just using the key in either door lock.

    Hmm... The question is, is there an ACTUATOR in your driver door?

    In any case, it appears that there was a running change in the 328 line. At some point (maybe around s/n 70000-ish) it seems Ferrari made the two door locks sync'd up, and it's not an "1988.5" change.

    --Mike

    Can any other 328 owners report? Do I need to make a poll? :)

    My 88 328 GTS Ser # 75391 , Both locks control both actuators in each door together...

    If one of my doors is not closed all the way, the car will not let me lock either, it will re-open the lock when trying to lock the car.

    I am glad this is like this, because currently i am haveing difficulty getting the friken key in the lock on the drivers side. The small black spring loaded closing cover in the lock will not spring open unless i take a small screw driver and open it manually to get the key in. I tried lubricating it, no help...

    The 308s have an actuator in both doors but only one (the pass side) actually pulls the lock down. The drivers door when it is manually locked sends a signal to the pass. door and that actuator pulls the lock down. Back to my original statement which is on a 308 unlocking the pass. side doesn't unlock the drivers side but locking the drivers side locks both.

    328 maybe different but this is how it works on a 308QV.

    I looked over the TSB list, and there doesn't appear to be any production change on the door locks on the 328. Both the '87 and '89 wiring diagrams show actuators in both doors. The driver's side actuator gets power from fuse 3 (15A, always on) and ground at the door, and two wires run between the driver's side actuator and the pass side actuator (which doesn't get separate external power). There's no separate "controller" box, nor input sensors -- they're all in the actuators (which are mechanically linked to the lock and key mechanism).

    On my early '88 (75207), the two doors are slaved -- they follow each other. If either door thinks it's not closed, both doors unlock. (Lock with the key, and both buttons go down ... and back up again.) (No external sensors, so it must base that "open" detection on the movement of the lock linkages).

    For any 328 where the driver's door doesn't follow the pass door ... well, these cars are 15-18 years old. That's "really really old" in electronics "dog years". ;)

    Hi guys,
    I have followed your thread with interest, as I am in a similar situation.
    My '95 456 has power locks, but no keyless entry, so I was searching the market for a suitable unit to install.
    I looked at the Crutchfield one, which seems to be fine and it could easily be installed in either door, as like in other Ferrari, on the 456 when you lock/unlock either door, the other door will follow.
    However, the question is how to deliver the input from the keyless relay to one of the actuators: mechanically or electrically?
    Mike, how did you do it on the Honda?
    Tks,
    Saluti,

    Honda did not need actuators, it had motors already built in.

    On the 328, I replaced the door lock actuators with a more standard, 5-wire design that I could work with.

    At the time, the alternative was to "piggyback" a modern actuator onto the driver's actuator, but I could not find a suitable place to install it. New actuators on the other hand went in in a matter of minutes. I even reused the wiring that led into the doors so did not have to rerun any new wiring.

    In retrospect, I think with a lot of hours, the wiring diagram, and a multimeter, you could probably find a way to interface to the existing actuators, but my attempts to do so in a few hours could not provide anything workable. There are lots of relays involved and things get even more complex if you want driver door unlock priority (which I did). The existing actuators are a little strange, each has four wires and grounds/voltage are being swapped dynamically based on state of the locks, so that each actuator was also a switch for the other one, and there were a number of states to track, e.g. out-of-sync with master, etc.

    Most straightforward solution is to replace the actuators, which is a fully reversible modification and the new actuators plug right in to the standardized drilling mounts (if I recall correctly).

    The 456 may be different, though! You won't know till you actually get a look at the actuators. Are the 5 wire or 4 wire or...?

    Interesting: thank you Mike.
    One final question: before you settled for the Crimeguard, did you look also at the Spal-Usa units?
    Regards,
