New to the 3rd Gen....any way to remove/disable factory alarm?

[Malcolm99]

dealer install is still aftermarket IMO, if its that troublesome snip snip, I'd go for the horn first and see if it lets you start it, if its still a problem lots more cutting and soldering. I've heard of a few dealer install alarm systems come up recently as problematic, feel sorry for everyone that got that port installed RS3200 box under the seat and got it wet.

agreed. I probably just need to get a 2002 wiring diagram, and start tracing wires backwards from the alarm speaker itself. There is a small silver module under the driver seat....not sure what that is.

I conducted a little test....opened the car, got in, closed the door, and sat there until the alarm chirped. Then I tried to start the car with the key. It would not start though it doesn't say "immobilizer" anywhere near the ignition.

These 4runners have an Alarm? You sure it's OEM? Mine is 100% OEM and is only keyless entry (lock, unlock doors and roll down rear window). The key is chipped for an immobilizer system, but that's just a start/no-start system. There's no siren, which is what I associate with an alarm.

Try checking the wiring loom that runs to the back hatch (next to the drivers side hinge of the hatch) for breaks/burns/damage as that's a known problem area and would impact the function of the keyless system (brains are in the hatch).

Maybe there's a difference between the '99 I have and your '02?

That could mean the immobilizer system...... and I don't recall mine having that sticker (but I'm the 2n owner and the windows are tinted).

- All '99+ 4Runners have factory remote keyless entry
- All '99+ Limited's have an immobilizer (chipped key) that is *not* an alarm
- All '99+ 4Runners had the option for a dealer/port installed RS3200 alarm

The RS3200 alarm should be easily removable. The other two (neither of which will honk a horn or make any loud noises) are not easily removed.

The '96-'98 4Runners are different - RKE is only part of the RS3000 optional alarm system, which installs much like any aftermarket system (also dealer/port installed).

Thanks for the info Charlie! So it sounds like my 2002 SR5 has the keyless entry, and the dealer installed alarm, but does not have the immobilizer as the key does not have a chip in it.

I managed to find the RS3200 installation manual for the 2002 Tacoma....cant find the 4Runner installation manual. I'm hoping that they're similar enough that I can back track through the installation and remove the entire RS3200.

I've read through it twice now, and while long, it looks pretty straight forward. The entire harness for the RS3200 just plugs in series with various connections throughout the truck....mostly under the dash and one under the hood. Ideally, if I'm thorough, I can trace the RS3200 harness back, unplug it, remove it, and reconnect the factory harness to the given component and SHOULD have no issues....
