Keyless Entry / Immobilizer Disabled

Last night I purchased a 2006 Acura RL. I was told it was a repossesion and therefore had no key fobs or original acura keys. They are flat metal (unchipped keys) and are branded "Ilco" which leads me to believe that are locks and ignition cylinder where changed out and the immobilizer was disabled. The basic key works for the doors and ignition. 3 turns of the key still put the windows and sunroof open or close them based on unlock or lock direction. My question is if there is anyway to get an original acura key fob programmed for the keyless entry only, without going to an aftermarket unit? I understand that I won't be able to do remote start, which I am fine with, but I would like to have the keyless entry. I am open to any suggestions anyone may have.

Thanks in advance!

3. If you want easy... go to the dealer, ask them to sync a key fob and hand over 500 dollars.

The immobilizer was likely disabled by locating one (a key fob) in the car somewhere.

I don't see how the immobilzer can be disabled. Do you see a constant-on key light on the dash? That's the sign that the immobilzer is not seeing a known key. Do you even see that light go on when you first turn on power to the car?

If there was a key fob located in the car somewhere, he'd be able to start it with no physical key at all. That doesn't sounds like the case.

I'm stumped...

The way I read it, the key is for unlocking the door...
can't do without it, but that's all it's for.

Reading is fundamental. If the FOB is in the car it would beep when the doors are shut and yes it would start with out the key.

...and what if the dealer threw away the little default black handle on the ignition switch
the OP would likely assume he needs the key for the door and the key for the ign

When I looked at the ignition, I only see a little piece of black plastic remaining. Looks like it was ripped out. They key that I have is used to both unlock the door and start the car. It works in both. I also noticed in the message center that it stated that the keyless system has an issue and may not work.

Normally we can come up with a way to avoid people having to visit the stealership, but that appears to be your number one option.

I'm fine with that, i just want the keyless entry feature . I will try to give them a call this week to see what they say and can do.

I am fine with an aftermarket keyless entry system, if that's what I need to do.

thats the path of least resistance, and worst case you just get an estimate.

They can check that all the necessary pieces are working, sell you a FOB, program it, and warranty the work.

Then if it fails you are mildly covered if/when something fails.

What I would be prepared for is if one of the door handles failed, that could be another issue on its own.

It may be a stretch, but I would be concerned that the RL is still programmed to the original fobs. Do you know that you are not in the locale of the owners from which is was repossessed? RLs are not that common and you could be a victim of exclusive coincidence.

I agree with the above posts. The dealer is your best option to 'reset' the proximity / immobilizer features. It will not only reset the security of the car, but then you have engaged the dealer as to the security liability by performing the spec work.

I still don't get how they disabled the immobilizer since you said you just have a normal (non-chipped) key. It would take quite some work to bypass that system as it was designed specifically to prevent people from being able to start the car without a programmed chip-key.

Can you snap photos of the key, the ignition switch, and the instrument cluster when the car is running?

A picture is worth a thousand words and will give all of us a better idea of what is or isn't normal on your car.

I wonder if the dealer's diag/setup computer really could do the disable? I'd sure be surprised if that's possible.

Then again, I have no idea how the immobilizer works:
prevent turning the motor over with the starter ?
cut the ign or fuel ?
all of the above ?

Anyway, you can't live without remote keyless entry and even better the proximity fob activation of the door handle unlock/lock is super nice.

The dealer HDS system CANNOT disable the immobilizer... There is no such option. You can replace the immobilizer and re-sync the new one to the ECU, but that's about it. The immobilzer cuts fuel so no start and it's tightly integrated to the ECU, so unless you can get the car to run without the ECU, I don't get how it can be easily done.

That's why I'm curious to see pictures...

How do we know the immobilizer is disabled? Is someone suggesting that if I have an exact copy of my physical key but no fob, I cannot start my car?

That is my understanding. The key must be chipped.

So what is the point of having a physical key? If the fob or the immobilizer malfunctions, the car won't start?

If you have an exact copy of your physical key WITHOUT being a chipped key... then YES, you cannot start your car. The FOB and key are separate things. Forget about the fob altogether... if you look at just your key (the one that snaps into the fob)... the black plastic head piece contains a chip that the car recognizes and will allow start of the vehicle with the physical key. The point of the physical key is to allow you to open your door and start the vehicle should your FOB battery be dead.

The OP said he has Ilco keys with NO chip. And he says that's what he uses on the doors AND to start the car. Thus, if that is really the case, the immobilizer must be disabled somehow... which is what is leading me to wonder how that is possible.

^ I'm wondering the same thing.
Seems like it would have been easier and not that much more costly if at all for the reposessor/seller to get a new FOB and have it programmed.

EXACTLY! It would be FAR FAR easier for someone to either get a replacement FOB or replacement KEY programmed into the car than it is to try to disable the immobilizer. Doesn't make sense. That's why I want to see pictures!

I am currently out of town on business travel and the car is at the airport. When I get back (late Friday night) I will take some pics of the ignition, key, and dash. I didn't get a chance to call the dealer yet. I am trying to do that sometime this week to at least setup an appointment and see what they can do. The car was repossessed in 2010 in Michigan. I live in Southeast Ohio.

Hopefully you did not open the trunk lid with the button on the door when you parked car at airport and/or previous owner had the software updated.
But if you have a dead battery when you get back, that would be the reason

Edit: Actually, not sure that this problem was in 2006. Was for sure in 2005.

Speculating again....

But I remember reading a post where an RL owner configured a remote starter by taking the OEM physical key (chipped) and hiding in the dash so the immobilizer recognized the key and permitted the remote start device.

Is it possible the re-seller of the car kept the fobs but put the physical key in the car somewhere and cut another set? That way the immobilizer would be satisfied and the cut keys would 'replace' the fobs they kept?

Still, my concern is that the RL is programmed to fobs / chipped keys that you are not in possession. I would want that changed as I would want the locks changed on a new house.

I guess I'll find out

I sure did use the trunk button on the door at the airport.

That is definitely one possibility, although why would one do that? They might as well just use the original keys. Why hide an original and then make duplicates?? I can understand keeping and selling the fobs, but keeping the original keys does you no good... no one is going to buy a cut key that doesn't match your physical locks. And it's not like you can recut them or even reuse the chip somehow.

Exactly. There's a key (or fob) or whatever the proximity device is somewhere in the car (dash, steering column).

I figure the dealer had only one key and copied it several times for the new owner to have more than one. Don't know about RL's but it's common on a Toyota with a remote start to require a chipped key stuck inside the steering column near the ign key lock cylinder. The chip has to be in close proximity to its sweet spot.

Another even more likely possibility is that the car had an aftermarket remote start (with chipped key stuffed in the column) being a cold weather Mich car and the dealer cut some plain keys based on the vin number.

The pictures of the instrument cluster with the car started will confirm this. If there is no Key indicator lit, then the car sees a chipped key somewhere. If it is lit, then something else is going on.

I remember when I first joined and only checked this forum once a week. Now, I am just a whore.



This has minor resemblances to the person who lost their key in the car, and we all told him against his belief it was there. He came back eventually, and it was.

OP, do you have the cover/key that comes with the car and is used when the fob is present? If that works, we would know the chip must be present then as well.

I'm a little confused on the key icon that lights and then goes out during startup. So, if the key is not present that light will stay on? But, how does the car start if the key is not present and the immobilizer works?

Wondering the purpose of the key icon light
