From my manual on a '99 Camry with a Carbine alarm system (Programming)

What I have on programming the Carbine alarm system transmitters.

1. Switch the valet/override switch into the off position.

1. Turn on the ignition.

2. Switch the valet switch on the off two times. The siren will chirp 1 time. You are now in the transmitter code programming mode. The LED will be a solid red.

1. Push the arm/disarm (regular two button, from the diagram) or Lock button (Code Hopping, four button, from diagram)

The LED will begin flashing slowly and the horn/siren will emit 1 short chirp. The code has now been learned.

Note 1: If you are coding a "regular" transmitter go to step 5. Note 2: If you are coding a "code hopping" transmitter, skip step 5 and 6 and go to step 7. No further coding procedures are necessary. Code hopping transmitters learn all button functions when the "lock" button is learned. Note: 3 You cannot code "regular" and "code hopping" transmitters to the same security system.

1. To code the #2 button, switch the valet switch on then off 1 time. (the LED will be solid red and the horn/siren will chirp 1 time.)

1. Push the #2 button. (the LED will begin flashing slowly and the horn/siren will chirp 2 times.)

2. Turn off the ignition. (the horn/siren will emit 1 short chirp and 1 long chirp. You are now out of the consumer transmitter code learning mode. The LED is off.
