How much cost is it to make a key of Honda accord car?

The key of my car is lost

Less than $2 if it is not a key with a chip. If it has a chip it will cost over $100.

They are expensive, if a newer Accord, because of the electronics. I think $85 to $125?

It doesn't really matter, you have to have a key.

1.25

Most Accords these days have an immobilizer that works with a chip in the key; the gizmo doesn't see the chip, the car doesn't start. The days when you could get keys for $1.98 at the hardware store are gone forever. Plan on spending at least $100.

Chip or no chip? If it's a chip key, it's going to be at least $100. If not, just go to your local hardware store and have it cut for under $10.
