Lost your key fob or need to program a new one for your 2001 Lexus RX300? Programming your key fob yourself can save you time and money compared to dealership services. This guide provides you with clear, step-by-step instructions to program your 2001 Lexus Rx300 Key Fob, ensuring you regain remote access to your vehicle quickly and efficiently. Follow these instructions carefully to successfully program your remote.
Step-by-Step Programming Instructions
To begin the programming sequence for your 2001 Lexus RX300 key fob, ensure you are ready to follow each step precisely and within the given time limits.
Step 1: Preparation
Start by removing the key from the ignition switch. Make sure the driver’s side door is open and unlocked, while all other doors are closed. This initial setup is crucial for the system to enter programming mode correctly.
Step 2: Enter Programming Mode
This step requires a sequence of door lock switch operations performed rapidly. Within 40 seconds, press the door lock switch to the LOCK position, and immediately within one second, press it to the UNLOCK position. Repeat this LOCK-UNLOCK procedure five times continuously. After the fifth repetition, close and then open the driver’s door. This action signals the system to prepare for key fob programming.
Step 3: Select Registration Mode
Next, again within 40 seconds, repeat the door lock switch sequence from Step 2 – LOCK and then UNLOCK five times. Do not close and open the driver’s door this time. Instead, insert the key into the ignition switch. To select the desired programming mode, turn the ignition switch to the ON position and then back to the LOCK position. The number of times you cycle the ignition from ON to LOCK within one second determines the mode, as shown in the table below. Remove the key from the ignition switch after selecting the mode.
REGISTRATION MODE SELECTION
| Registration Mode | No. of Ignition Switch Cycles |
|---|---|
| Add | 1 |
| Rewrite | 2 |
| Confirmation | 3 |
| Prohibition | 5 |
| ——————- | ——————————- |
For adding or rewriting key fobs, use 1 or 2 cycles respectively. Confirmation mode (3 cycles) will cycle the door locks to indicate how many key fobs are currently programmed. Prohibition mode (5 cycles) is for deactivating key fobs.
Step 4: Transmitter Programming
If you selected Add or Rewrite mode, proceed with programming your key fob transmitter. Within 40 seconds, press and hold both the LOCK and UNLOCK buttons on the transmitter simultaneously for at least 1.5 seconds. Immediately after releasing these buttons, and within 3 seconds, press any button on the transmitter for at least one second.
Step 5: Confirmation
Wait for the system to respond. If the door locks cycle once within 3 seconds, it indicates that the new transmitter code has been successfully accepted. If the door locks cycle twice, the programming was unsuccessful. To program additional transmitters or retry, return to step 5 within 40 seconds.
By following these steps, you should be able to program your 2001 Lexus RX300 key fob efficiently. Ensure each step is performed accurately and within the time limits for successful programming.
