Why would Honda charge so much for a spare key?
The answer is simple, I'm afraid: because they can.
The Honda key isn't just a simple piece of metal, but a also small transmitter AND probably a small transponder (I know Fords do this), too. With the key in the lock, the car electronics talk to the key and back through very low power transmitter to check the key's unique serial number. No matchy, no starty.
Now, all very clever, and DELIBERATELY hard to duplicate - that's the whole point, after all. So no one else other than Honda is going to be able to make spares.
So - Do the keys cost that much to make? Nothing like it.
But then don't confuse purchase cost with selling price. An item costs a manufacturer what it costs him in time and materials. He will sell it for whatever he can damn well get away with. And while Price >> Cost, the manufacturer has what we call a business.
£190 quid, though. They must be 'avin a laugh. (and I bet they are)

(Got me a Jazz EX I-shift, btw. Nice. I shall be paying a LITTLE EXTRA ATTENTION about where i leave the keys from now on!)
