Immobilizer light - 2009 Toyota Camry Hybrid

Possible causes: Damaged antenna, lack of synchonization with the key, electronic failure with the immobilizer or the computer it accesses. This well may call for a Renault specialist to diagnose but here is what you can try:

To address this issue, consider the following steps:

1. Disable Immobilizer and Start Engine Without It:
   • Obtain the pin code (usually available from the immobilizer itself or through dealers).
   • Try starting the engine without the immobilizer. If successful, this indicates an immobilizer-related issue.
2. Inspect Soldering on the Immobilizer:
   • Visually check the quality of soldering connections on the immobilizer.
3. Remove Aftermarket Devices:
   • Turn off any additional devices (e.g., aftermarket radio) that were not part of the manufacturer's original setup.
4. Check Wiring Integrity:
   • Inspect the wiring for any visible damage.
5. Verify Lighting and Reversing Lights:
   • Ensure proper functioning of lighting systems.
6. Consider Temperature Effects:
   • If possible, leave the car indoors to avoid extreme cold, which can affect immobilizer performance.
7. Check Neutral Position:
   • Confirm that the transmission is in the "neutral" position before starting the engine.

Anti-theft system problem , possibility ! Do you have a security light blinking ? Security Indicator
The security indicator is located in the clock on the top of the instrument panel. The light emitting diode (LED) displays the immobilizer system status. The immobilizer contains the LED driver hardware for direct connection of the LED.
Vehicle Theft Deterrent (VTD) Operation
The immobilizer system design prevents vehicle theft by interrupting the engine operation. The immobilizer system prevents the vehicle from starting. The engine operating functions interrupt if the immobilizer system does not recognize the transponder identification code of the ignition key. The immobilizer system and the content theft deterrent system do not interact. The system includes the following components:
?€¢
The ignition key

?€¢
The column-mounted theft deterrent module with integrated antenna

?€¢
The transponder

?€¢
The engine control module (ECM

try using a scan tool to reset the immobilizer system
remember that every time the battery is disconnected the immobilizer activates

OK, if the vehicle won't start and the service immobilizer light is on then I would definitely take it to the dealer in order to have the key programmed to the computer, again.

Did the battery go dead lately? Is there a code associated with it not starting, as in the immobilizer function lamp?

or the key is not programmed to the ecm?

P0633 Immobilizer Key Not Programmed ECM/PCM
This is just a possibility to look into.

"Security" or Key-shaped light flashes on the dashboard ? Your car might be equipped with an immobilizer. (you can find more information about the immobilizer in your owner's manual). The immobilizer allows the engine to run only if the correct key is used. If your car has an immobilizer, you probably see a "Security" or Key-shaped light coming on on the dashboard every time you turn the ignition ON. If this light is flashing when you turn the ignition ON, it could mean that there is some problem with an immobilizer or the system does not recognize the key. If the immobilizer doesn't recognize the key, the engine wold not start at all, or would start and then die in few seconds.
You can try a spare key, if it won't work, your dealer is the place to call. Sometimes, the key is just need to be reprogrammed.

An immobilizer bypass is an electrical circuit which allows current to flow to whatever component is starved of current to keep the engine from running (usually the coil). The immobilizer opens the circuit to the coil, the immobilizer bypass closes the circuit to the coil.

If you didn't install an immobilizer circuit, then you don't need the bypass. There are probably instructions you missed in the manual explaining the immobilizer circuit.
