Just a heads up in case anyone else confronts this.

The use of Radio Frequency Identification, or RFID in Ignition Keys is common now days among manufacturers and their various models. I will share a story concerning how this technology recently affected my wife and me.

As most of you are aware the Ridgeline Master Ignition key is not a key in the traditional sense. If you examine it, you will notice that it doesn't have real teeth cut in it. The key contains an electronic chip that has a code (Lock) embedded in it.

When the key is inserted into the Ignition Switch and turned, the vehicle's computer system electromagnetically reads the code on the key and verifies that it matches the code stored in the vehicles memory. Assuming that it does, the engine will start as usual. So far so good....

Many of you may not be aware of the conditions that exist to immobilize the vehicle should the confirmation fail. (Vehicle Theft Deterrent). Essentially, the engine's fuel system is disabled. This information is available in the owners manual, but how may owners read the entire manual and remember it months later?

This is what occurred with my wife and me. I had to work late several nights in a row a couple of weeks ago. Out of pity (or maybe love;) ), she delivered dinner to me one night. We intended to swap vehicles when she left, so that she could protect my baby from the upcoming storm. When she went to leave in the Ridgeline, she could not start the engine. She called my cell, I went out into the parking lot and tried to start it several times myself. The engine would turnover like normal, but it would not start. We called the dealer, who is only a couple of miles away, and has late night service department staffed. They asked the typical trouble shooting questions over the phone, but not the right ones. My service rep agreed to drive over to meet us. We hung up the phone connections. While still sitting in the drivers seat, I happened to notice that my wife's keys were in the ignition. I removed hers and inserted mine and the truck started fine. Called the dealer to stop the rep from coming.

My wife's key has lost her program. She hasn't been through any security readers like at airports, court houses etc. Never submerged in water or cooked in the microwave oven as the dealer suggested. Maybe they could have been dropped a time or two.

The only feedback from the Honda system that signals that the key is not right, is that the green key symbol on the dash will blink with the "Bad Key" switched in the "On" position. It is not that noticable.

Anyway my wife is still pissed. She does not see this as a security answer at all. She says it's only a safety device if it prevents SOMEONE ELSE from starting our vehicle. Her key should NEVER lose it's program! She's going to throw the key in the garbage because that's what it is - trash. She's not carrying it with her. She says it's baggage at this point and has no value. (J-man did not type this paragraph. I, Cindy Hedges, did!)

So in a nutshell, if your Honda will not start, check for the Green Flashing Key Symbol on the dash, and go get your key reprogrammed.

Well, Cindy Hedges, the keys are pretty expensive to replace. Chalk it up to Murphy's Law. Also, the situation could have been worse. It could have happened in the middle of nowhere at 1:00 am and your cell phone is dead.

Anyway, J-Man, thanks for the story. I wonder what caused the key to lose its programming. Weak or dead batteries, magnetic source in purse, Magneto, abducted by aliens, microwave, etc.

Actually, dead batteries wouldn't have anything to do with it, would it?

I see by your public profile that you are an engineer. Perhaps some of your buddies can help find out what may have caused the key to lose its ID.

Visited this site, but it didn't really tell me what may cause the loss of info.

Had that key ever started the Ridgeline? Maybe it was never programmed into your RL to start with.

Also, based on what you've posted, can you use the same key for 2 Ridgelines if indeed it is only the code and not the shape of the key?

While the physical shape of the key is not sufficient to start the vehicle, it is what allows the key to physically move the ignition from one position to another. It _is_ sufficient to open the driver's door, glovebox and trunk.

I see three possible scenarios:

1 - the vehicle was never programmed to recognize the key's ID

2 - the vehicle "forgot" the key's ID

3 - the transponder/RFID-chip in the key malfunctioned/broke

my vote is for #3

Thank you for the information.

I see that vertrkr provided instructions on how to program the keys ...

I have to ask the same question as swampler ...
Did your wifes key ever start your RL?

I recall on the ROC checklist for RL delivery is to verify that both keys operate in all functions.

Did your wife set her keys down on any department store counters?
If you've bought pretty much anything lately, you may have noticed the cashier rubbing the item back and fourth on the counter for a few seconds. No the cashier doesn't have some weird OCD tick, they're diabling the RF tag from triggering the alarm when you walk out the door. You put your keys down on that same spot and you may be in for a world of hurt when you try to drive home.

We need fingerprint scanners already ...maybe some retina scanners.
