Disabling horn noise on remote locking and unlocking

I can answer my own post for those with the same issue. The manual is wrong. To disable the horn, open the driver side door, turn the key on and then off. Behind the alarm light unit under the dash, above the parking brake, there is a button. click this button 3 times and voila, no more horn!

What vehicle is that for? When I bought my '04 Tacoma I just followed the noist till I found the piezo and disconnected that. Is there another way?

I think he's talking about a different noise. His noise is the car horn when you hit the remote lock button, yours seems to be when you open the doors, or leave the key in the ignition, or leave the lights on.

You're correct. It is an '05 Tundra Access Cab. I wanted to disable the horn sounding when you locked or unlocked with the keyless remote. Now it is a much less obnoxious electronic beep.

Do you have an alarm installed?

Do you have an alarm installed? No, unless there is one that comes from the factory on it.

I miss understood you. I thought you was talking about the chirping noise it makes, when you lock and unlock the doors with the keyless entry remote.

Read the manual. That puts it into "Valet" mode, which stops the horn.

I found the 2005 Tacoma security to be a real Pain in the ___. For example, if you lock the truck with the remote - and then unlock it with the key - the alarm goes off. I complained to the dealer and he said: "Yep, that's the way it is."
