Hi,

2006 EX with the fob integrated with the key.
Went to Ace Hardware. Ace is where I successfully bought a key for this same car a few years ago. But a different Ace where I used to live.
The key from this new Ace opened the door and turned the ignition but would not start the car. Just turned over and no start.
So then went to Batteries plus and same thing.
He said go to dealer but they are $75 more.
Anyone know whats going on or another option?

Thanks!

This all started when my plastic case broke. Then I lost the transponder chip. So I now have a plastic case with a properly cut old key that I used for years, and the guts (electronics) that used to work but now when I go to the car and press the button the red light on the electronics lights up but the car does not respond.

And I guess you can't buy a new transponder chip, I don't see them for sale anywhere. I guess that's part of the control for our safety and security.

That is strange. Using a key with no transponder should have prevented the engine from starting. You say you used it like that for years??? Losing the transponder? You can buy the right key with transponder and then have it programmed to the immobilizer.

For me, I installed a remote starter. It uses the key's fob's control buttons (the lock and unlock) to start the engine. Programmed the keyless entry remote (on 2007 CRV) and I can start the engine. The use the key to turn it to run and take over without having to shut the engine down.

The key that had no transponder was not opening the doors. After I did the reprogram it opened the doors.

It does not start the engine. That's why I said I would have to tape and hot glue the transponder to the key lock cylinder.

But if the ebay key fobs can be programmed the same way, then I won't have to do that. We will see in a few days.

Yea I lost the transponder. I saw it fall out, it had some cardboard or something wrapped around it, I had no idea what it was, and must have thrown it away I think.

I know I can buy another key and have it programmed, which, without a working transponder, would be about $150.

I read one place that some locksmiths sell just the transponder chips for about $35.

But I now have a second key fob with the proper metal key cut and it just needs a transponder. The ebay replacements say they come with the transponder chip, so I'm going to see if I can get that to work. Others reported that it worked for them.

The problem sounds like getting the transponder to be recognized by the immobilizer. For that, one needs a higher level scanner that does programming (bi-directional??). Locksmith should have it. They are always offering to do it when I have an auto key cut. Honda keys are like $40 and Toyota keys are like $6. And that is just to have the blade cut.

Note: The issue with gluing the transponder to the key cylinder is that then it will only take a screw driver to jam the lock cylinder and then a vice grip to turn to to get the engine started. That is what happened to my old Pontiac. No immobilizer back then. They jammed a screw driver in and popped the lock cylinder out and used the screw driver to turn the ignition and start the engine. Car was never the same afterwards.

OK well I ordered the keys from ebay and I'm going to try doing the thing in the video above. If that doesn't work I'll take those to the locksmith. But others reported that they did that trick and it worked.

I know gluing the transponder sets up that risk. But the chances of my car being a target are very slim. And what thief would know that it was in there?

Plus, I hardly park anywhere that there are thieves. I live in the country, where most people's keys are in the ignition or under the mat, or above the sun visor...not mine tho...

Plus after I roll it with massey furguson grey rustoleum tractor paint no one will want it.

I called around and places quoted $185, $150 for just programming a key that you bring them.

Then I found an ACE (JB Zimmerman in New Holland) that said they would do it for $25.

Great guy there Drew tried 2 keys I bought on ebay, did not work.

Next day my wife wanted to borrow my car, and she said she had a key on her keychain. It did not start the car, but she said it worked before. It was an OEM Honda key with transponder and no other guts.

And, I received 2 more keys from ebay from a different seller.

Went back to Drew at Ace this morning.

I put the OEM Honda transponder in one of the keys from the first ebay batch that Drew cut last time. He got that one to start the car. OK, one win, now I have 2 working car keys and don't need to go to the dealer.

Then Drew tried the 2nd batch of keys from ebay. Did not work.

I asked him if he usually gets most keys to program. Yes. I asked him where I should buy keys next time. He said Amazon. I said that I had a hard time finding one there, that's why I did ebay. He said maybe you can find just a transponder for sale somewhere. I said I think I looked for that and could not find it. I will look again.

I gave him a $20 tip and said thank you for being persistent. You are the only one within an hour from me that will do this for anything less than $150.

He walked me back to the register and got me a refund on two cuttings and one programming. So I ended up paying $25 for one programming.

Does anyone know where to buy replacement keys that they have successfully gotten programmed?
