Introduction

Difficulties during Remote Keyless Entry Transmitter Programming can arise due to confusion between Toyota Factory Wireless systems and Toyota Port/Dealer installed systems. This bulletin will assist in identifying the system/correct remote transmitters for each vehicle, and provide the location of the most accurate programming procedure for each system.

Applicable Vehicles^ All applicable Toyota vehicles.








Warranty Information

System Identification

















The table contains all of the necessary information to correctly identify the type of system installed, and where to go to get programming procedures for each vehicle.

NOTE: Should a vehicle having both VIP and Factory systems available (as identified in the following table) be brought in without any remotes (or one non-working remote), use the following tips to help determine which type of wireless system (O.E. or PIO/PIO) the vehicle has.

^ Look at the Trim Level of the vehicle. Higher-grade vehicles will tend to have O.E. systems, while entry-grade vehicles will tend to have VIP For example, the 2001 Camry XLE has Factory RKE, but the LE and CE grades have VIP.

^ Look for a "Status Monitor" with a glass breakage sensor and an LED externally installed into the dashboard or on the center console. Most VIP systems will have this.

^ Locate the ECU (refer to the applicable vehicle VIP Manual installation instructions for location). Once located, refer to the part label.

^ Attempt to perform the factory wireless programming procedure to get a response from the vehicle. Select the "confirmation mode" and see if any "Lock/Unlock" response is received, if so, the vehicle has a factory system.

That is the keyless entry system without immobilizer.
