Installed a "slaved remote start" unit in a 2002 toyota tocoma. Can start truck with the OEM keyless entry remote, entire unit fuctions as advertised. Problem: once the truck starts, the OEM unit doesn't function. I must unlock the doors with the key to enter the truck. Would like to override the system to be able to enter the truck using the keyless entry. In stock form, the remote doen't function if truck is started. Thought of resuppling 12 volt power to the VIP secuity brain to allow use of keyless entry whilst truck is running.

i am makin a reference to honda vehicles. i hope you can get some idea of it, but not the exact.
-when puttin in the key it automatically discon the power wire to the keyless. hence when puttin in the key there should be a beep sound keep goin off, and this is where the wire that makes the keyless have no power. there should be couple wires-harness that goes to the keys cylinder, just discon one of those harness and see if the sound cuts off.
-and there is an ignition wire at the keyless. test it with a DMM and cut it off or use relays to cut it off the two wires (but too much trouble there)
and dont forget to put a diode to your RS initiate wire.
dont discon the yellow wrap harness(airbag).

This is why it's better to just get a good long-range remote start that comes with its own keyless.
Disconnecting the keysense wire as profuse007 mentions, will not enable the keyless on a Toyota. Since you don't leave a key in the ignition during remote start, the keysense wire is dead anyway, until you insert a key.

I clipped the "cylinder" wire (light GREEN/ red) and also the "ignition" wire (BLACK / YELLOW) at the alarm brain. Everything works as I intended. Thanks for the advice and responce!

If you clipped the ignition wire, how will the alarm know that the car is running? You don't want the alarm armed while you're driving....unless I'm missing something. In my girlfriend's car, she had the same problem. I cut the alarm's ignition wire in half, and wired it to a relay and to the remote starter. So when the car is remotely started, the keyless still works, but the alarm knows to shut off when you're drving.

well this is not intend for everycar. this works well with Honda keyless, because it doesnt arm automatically(actually you can set to passive or active lock). but i was making a reference to Honda only. but this installer might have you case, cause toyota seems to have passive arming. so the only disadvantage is disarm it after he or she gets out.
there is not much a stock unit can do. but finding a better pupose in having remote start will have to violate some rules.
hell, if someone like to put RS in there stock unit that have passive arming. tell them to cut off the horn to the unit. beside it's only a piece of sh*t "alarm". no offense cpgoose.
99.99% who owns stock keyless system only want keyless sytem, they dont care about the door-trip alarm.
