Hey Scotty,

I'm 15 and I found a old key for my parents 2003 Lexus RX300 with 59K KM in Hong Kong so I taped the key back together and it did not have a chip and tried to start my car and it turned the anti theft immobilizer on I've tried many different things on the internet. The car still won't start with the original key that normalIy starts the car. I scaned the car with my bluedriver and got the code B2796 and the VSC and ABS lights started flashing. Please help


I have access to a garage as I have been working at a garage for around 2 years now

Take responsibility for your actions and tell your parents what happened.


Even if I tell them either way I'm gonna have to fix it


Their key will probably start it


I used their key it still didn't work that's why I'm panicking


Just for the sake of "learning a lesson" & pretending the correct key won't do the job, they probably would want an actual mechanic to fix it, not the kid who was trying to go on a joyride.

When you get your own car do whatever you want to it.


They make me fix everything that breaks at home and in the car because I have a job at a garage and I've been there for around 2 years


Call the dealership. There’s probably an unlock procedure

My thoughts are 3 fold depending on the amount of time remaining before impending demise.

1) Join a Lexus forum-anything and everything that has ever happened to any vehicle has usually been experienced by a forum member. Likely someone has an answer. It may not be one you like but it is what it is.

2) Disconnect the battery-leave for 2 hours and hope

3) Barring those-you need to do one of the following based on your relationship with your parents. As a father of 3 who are in their 30's, I saw it all. Obviously, I don't know your mom or dad or their personalities so you will have to judge which is the best way to go based on your instinct of their reaction.

Pick one to talk with. Whoever will have to deal with the issues you accidentally created will be the one you should go to.

Your lesson here is not "don't tape a broken key and put it in the ignition". You were curious. You thought you had found a free extra key. I did many a thing in my youth out of curiosity with no ill intent which taught me lessons. It still happens today so prepare for a lifetime of head scratching and desire to bang your head on the wall. What you are learning here is why things work the way they do so you can hopefully apply that knowledge in the future to avoid problems, solve problems and/or help someone else. That is the simplicity of what is happening.

Now your next lesson is how to best handle situations with people-namely your parents. I'm just going to say your dad in this issue so I won't be deemed sexist.

Your dad may not get angry at all. It depends on his personality, your personality and your relationship. This is where you have to make the call on the approach.

If you guys are pretty close, you just need to be honest with him ie. I found an old key which I thought I could use for a spare if I needed it. I tried it in the ignition and now it won't start. I would not bring the taped part up but it may be unavoidable. If so, just tell him the truth-you thought that this could work and you'd have an extra key so you tried it. Yes, reactions are often unpleasant to experience but it's part of life.

If you have a major fear of consequences, a father that angers easily, or one that basically verbally abuses you for mistakes-here is my advice. I would tell him simply that your car won't start(for now). Just be dumb. Yes it is a lie to a point but bear with me here as this initially is counterintuitive. You may be doing him a big favor. Some people react where they just spout out whatever comes into their mind not weighing the impact or even knowing the reason why they said what they said. For this type of personality-as I said just play dumb- for now. Tell him you read up on some things to chase down on how to deal with these symptoms(do not mention the key-simply your car won't start. You got in and it did not start-period) but that nothing worked to correct it. You have to let him take his crack at it because it's human nature to seek simple solutions. Maybe he finds a way to fix it, maybe not, or maybe he is clueless in such matters. Barring the finding of a solution, it will cost $$$. While the first part of this is what some people call a "white lie", here is your redemption. Earn and save the money for the repair-without him knowing it. When you have it, give it to him. Tell him you found an old key which you thought would be a spare-tried it and then after that, everything went dead. Leave the tape part out-it is an unnecessary detail which just brings in a shock factor(you taped a key-seriously?) Tell him you feel bad about the situation and this is your way for taking responsibility. Sometimes people don't understand your reason for doing something. Sometimes you don't understand your reason for doing something. Always take "appropriate" responsibility, the timing of which you have to decide based on all the variables. Don't shy away from the fact that you make mistakes. You learn and you become wiser. A rational dad is proud, not that his son makes a mistake, but because he did the right thing to correct it..except criminal activity and serving time in jail.

Somehow, I think in a situation where a dad cares enough to provide a car for his teenage son and the son cares enough to take responsibility for taking care of it, you won't have a major problem. Trust me, you BOTH will learn something from this.

Hopefully your father is not related to Doc {black}:scared:  


Thank you for the advice but even if I tell him he will make me fix it as I intern at a garage but my shop is closed till Monday so I don't have access to any of the equipment till then and it probs won't cost me much as I've been working there for around 2 years


Problem solved. You will learn information that none of us currently know. Consider it a challenge {black}:wink:

Be honest about the incident with your parents. That's the only way they might not kill you. At age 15 you will be the prime suspect and you WILL crack under pressure. I have two adult children now and if one of them had confessed a crime similar to yours as a teenager my reaction would have been tempered by two things:

1. Thank God you couldn't start the car and go for a joy ride.

2. I did the same thing when I was 15 years old. There were no transponder keys back then so I actually drove the car. My parents found out anyway because a neighbor ratted me out. Your Dad may have a similar story he won't share with you.

Why were you using the broken key in the first place? Are you allowed to use the car? Or were you sneaking it out?

Also, have you tried the door trick?


It was just lying around and I wanted to see if it would unlock the car and I thought the car wouldn't have this system because its a 2003 and its pretty old. No I haven't tried it how do I do it?


Try turning the key for the drivers side door. Use a key that works. Lock it and unlock it. Let us know if it works or not.


I've already done that it doesn't work if I disconnect and reconnect my battery terminals will it solve my problem?

nobody could figure it out

Bite the bullet on this one, when you're caught, you're caught.

It's part of growing up & learning to not screw around with things that don't belong to you.

Why did you need to tape the key?


I had a old key lying around that broke around 10 years ago eventhough I have 2 working keys, that key that I taped did not have any battery or chip

What year and model? How many miles?


It is a 2003 Lexus RX300 with 60K KM

Before moving further, replace the battery in the key if there is one inside.


If this does not help, you will have to reset / delete the error code, and try again.


Okay will try this thanks


For your understanding: this code virtually says that the immobilizer module could not establish connection with the chip inside the key, which sounds legit, since the taped key you were using did not have a chip at all, right?
So the immobilizer module detected what it thought to be a car theft attempt, and did its job - immobilized the car.
Since this code is a security-critical one, it probably wont go away even if you disconnect the car battery (maybe it will, but chances are not high).
However resetting / deleting this code will most probably fix the problem. You will however need to get hold of a proper scanner for doing that.


Thank you, I have access to a dealer level scanner and will try it

What things did you try?


Many different ways of turning the key according to many different people on the internet and leaving the key in the car so it can register it took 2 hours and still didn't register. should I try to reset the computer with a garage level scanner?
