Article [13] ST1300 - HISS (UK) and Chipped Ignition Key.

The obvious fly in the ointment is the source of the chip. I've never had problems doing this.

Note paragraph 6 in the document that is attached to the first post in this thread in the section Register your keys. At this point you have the key that works in the ignition. "The red light comes on for 2 seconds and then flashes four times repeatedly. Which means that the system is in registration mode."

Note that when you register the second key, you have to take the first key out of the ignition, walk across the garage put it down. Pick up the second key - which you should have placed at the other side of the garage, walk back to the bike, insert the second key and turn on the ignition. If the antenna (that surrounds the ignition key slot) can detect the other key, then it will not work.

It has re-registered itself with the ECU and it now needs to set the same code for your other keys. If it cannot register a new key but it can re-register the old key, then I reckon that the 2nd key is the one at fault.
The only other possibility might be if the previous owner had obtained a new ECU and had a key made that works with it. Apparently that is possible, but from what I read a long time ago, you have to have additional keys cloned from the original.

The normal process is that you have to register the first key, and that then renders all other keys that used to work with the bike, useless - so if you have three keys and want to register a fourth, you have to start with a key that works and then re-register the other 2 and the new one. You cannot register a key that has already been registered with a different ECU.

The only way to find out is to buy a proper Honda key and chip. Fowlers have them in stock. They are about twice the price of the ones that I puchased and described in the pdf article.

Obviously, I cannot guarantee that that will work. But I am always suspect of anything that is a cheap fix, and there is only one way that you can find out.

Hi, thanks for your reply.

That’s all understood. I am following the procedure you described, keeping all other keys well away from the bike at all times. I just had another go and same result unfortunately.

I contacted the original key & chip supplier to see if they had any ideas and they were very surprised, saying they had done hundreds using those chips without any issues.

The chances of the first chip AND the more expensive replacement both being faulty are tiny, so I am reluctant to buy a Honda one as well, as it almost certainly won’t solve the problem. After all they don’t make chips, and PCF7936 is a standard chip. They are just marking it up.

My local lock smiths say they can clone the working key, but that will cost £80

I found out that this cloning process can be done at home using a “Handy Baby” tool, but they are £140 and don’t seem to exist second hand.

Interesting point about a PO changing out the ECU. I don’t know why that would stop it registering new keys, but who knows?

Interesting discussion here. They are talking VFR but they use the same HISS system.

Note that some of the participants use the word ‘clone’ when they are referring to the normal registration process - which doesn’t make an exact copy. With HISS, every key has a different number. Cloning makes an identical copy of a key that works so the Ecu doesn’t know the difference.

I’m out of ideas now !

Nb - you can start the bike with a standard key without a chip in it, providing a working chip is placed alongside the key when you start the engine. After that the chip can be put away somewhere. The engine will continue to run until you turn it off, or use the kill switch. It might make getting a chip cloned / cheaper. Once working the chip can be put inside the handle of a key blank with a space for a void.

Thanks John, I think I will go down the cloning route as for whatever reason my ECU is refusing to play ball, and the last thing I want to do is screw up my only working key.

Hopefully I can find someone who will do it for less than £80.

Just for info, you do need both a working key and the bike to be present for the cloning process. The cloning tool (Xhorse, Handy Baby etc) first reads the ID of the working key chip, then it “earwigs” on the codes exchanged between the key chip and ECU when the ignition is turned on. Finally it uses all this info to write an identical copy of the original key chip onto a new one.
