How long was remote left without battery. Information stored may be lost if the new battery is not in place fairly quickly. You may need to have your remote recoded.
I tried doing the programing instructions but with no luck. My old keyless was busted and taped together and there was nothing to attach the keys to. I took the outter shell of the new one and took the guts out of the old one and I am back in business)
Go to dealer.
If it is a quality battery it should last 3-5 years. Now if you run the battery down a few times you decrease it's lifespan. There is no way of telling exactly how long a battery will last. I have had them last 6 years and also had a few that lasted less than 2 years. I am replacing the faactory installed battery on my 2004 V6 Tacoma today. It is just over six years old and shows no indication of being bad, I am just being safe.
i have only seen that happen when you use the keyless entry system.
From $60 up to $200.

No . Have some mechanical assistant
the factory alarm is turned on and off by the drivers door-key-switch....or with the factory remote if you have one...unlocking the door with the key turns off the alarm...:)
disconnect the battery
under the drivers side dash board, and under the hood on the drivers side right behind the battery.
Check the fuses.
One reason why the wipers won't work on a 2005 Toyota Tacoma could be the fuse needs replacing. The problem could also be the wiper motor.
