Immobilizer bypass how to bypass immobilizer for my yzf 600 r6 2007 model put key in but still won't start.

you dont

Sounds like the Remote has Bypassed the Security System and once started, the Immobilizer is then become inoperative seeing that it got it's input from the Remote System itself.

Now when you attempt to start the truck with the KEY ONLY, it will not start. Look at the "Security" light when you are turning it over... Is it flashing or does it turn On or is it Completely Off?

Here is what I would do... Try your Other Key, if the SECOND KEY works, then your key has failed. If NEITHER KEY works, then your Immobilizer CODE is gone and for some reason as the REMOTE has bypassed the system it is allowing your to operate the truck.

When did the problem start to occur?

put fuse back in disconnect batt wait 60 seconds re attach, when the horn starts honking lock and unlock drivers door with the key while doors closed window down. get in car and start it, should be fine now.

Try starting the vehicle in another gear. If this happens, the problem is with your neutral safety switch. I have seen this issue on Chrysler and Dodge minivans and the owners changed the starter and the problem continued. It wound up being the neutral safety switch.

Sounds as if your immobilizer bypass is malfunctioning. To test, remote start vehicle. Check vehicle cluster (gages). If the immobilizer bypass is the issue, there will be car/lock symbol flashing rapidly. To confirm, put the key in the ignition(do not turn), remote start the vehicle. It should start. If the vehicle starts, remove key, remote start again without key. If the vehicle does not start, have the immobilizer serviced. If the vehicle does not remote start with the key in the ignition, the issue may be with the remote starter's starter output.

Hello
You can go to a locksmith and make anew key with immobilizer

Hi and welcome to the site,

Initially, check, clean, bypass or replace the sidestand switch.

Good luck and thank you for asking.

Code 52 indicates an immobilizer problem.- Probably "signal interference"
This model is equipped with a selfdiagnosis device for the immobilizer system. If the immobilizer system is defective, the indicator light error code 52 could be one of those displayed. This error could be caused by signal interference.
If this occurs, try the following. 1. Use the code re-registering key to start the engine. NOTE: Make sure there are no other immobilizer keys close to the main switch, and do not keep more than one immobilizer key on the same key ring! Immobilizer system keys may cause signal interference, which may prevent the engine from starting.
2. If the engine starts, turn it off, and try starting the engine with the standard keys.
3. If one or both of the standard keys do not start the engine, take the vehicle, the code re-registering key and both standard keys to a Yamaha dealer and have the standard keys re-registered.
Hope this helps

use your key under the left hand side of the seat cowling turn it,lift the back of the seat.

If your key is grey, and you would like to bypass the transponder system you need 2 working keys to program it, this kit comes with a bypass box, and a transponder loop, and only has 2 wires to hook up. Let me know if you still need to bypass it
