Can anyone tell me why sellers on eBay sell the BAB237131-056 as working for a 2002 Tundra when everything I read says you need the [FONT=Arial, Helvetica, sans-serif]BAB237131-022?

Not all 2002 Tundras came with the same alarm system. Some used one remote and others used another remote. I believe it depended on whether the alarm was installed at the factory or was installed at the distribution point or dealer. You need to look at your alarm ECU and find the FCC ID number. This will tell you which remote you need. The FCC ID numbers need to match.

I pulled my ECU and these are the only numbers on it.

Any ideas?

Are you talking about the engine ECU or the alarm ECU. The alarm ECU is what you want. Mine is located behind the instrument cluster and is taped to the steering column. Is this the ECU that you are looking at?

Pull off the foam that is covering the ECU on the side where the paper sticker is with the numbers you supplied. The FCC information is on the ECU under the foam. Mine reads:

TOYOTA V.I.P. Security System

MODEL:RS3000(08190-00921)
FCC ID:BAB 237000-129
CANADA:2024 101 527A

Mine uses the remote with this designation -
