1. Locate the valet button. The valet button on a 1999 Chevy Tahoe is usually located under the dashboard, on the driver's side. It may be labeled "valet" or have the word "valet switch" next to it.
2. Insert the key into the ignition and turn it to the "On" position. Do not start the engine.
3. Press and hold the valet button for at least five seconds. The alarm should disarm, and the LED light on the alarm system should turn off.
4. Start the engine.
Warning
Bypassing the alarm system without a remote may compromise the security of your vehicle and make it more susceptible to theft. If you do not have a remote, it is recommended to have a professional automotive technician bypass the alarm system for you. Additionally, bypassing the alarm system may void your vehicle's warranty.
Note
The exact location of the valet button may vary depending on the year and model of your vehicle. If you cannot find the valet button, you can refer to the owner's manual of your vehicle for more information.
