Keys for 06 & 07 Sonata

No need to pay the $30 from a dealer. My local locksmith charge $3 for a
key. He did not have the HY15 blank, so he modified an HY12 blank. It is a
solid metal key, no fat plastic, making it ideal for the wallet.

 

The actual key part can be cut at a good price but with out the the
electronic component that allows the remote entry and imobiliser I
would have thought the key could not be used.

 

Not sure if the AU or UK/EU versions are different, but the US version
remote is not an immobilizer. All ours does is turn on/off the alarm,
lock and unlock the doors, and open the trunk/boot.

You can start and drive the car without disarming it. It will simply
make noise and beep for a few minutes before it gives up and stops
sounding. Useful to know if you misplace the fob.

 

My 2003 Sonata will alarm if I open with a key after my wife has locked with
the fob. The 2007 Sonata is perfectly happy to be opened with the key in
the same situation. I prefer it that way since my RV is the same. Besides
keys are a lot smaller than fobs for my pants pocket.
P.S. where did that word "fob" come from anyway? not friends of bill

 

fob (n.) Look up fob at Dictionary.com
1653, "small pocket for valuables," probably related to Low Ger. fobke
"pocket," High Ger. fuppe "pocket." Meaning "chain attached to a watch
carried in the fob" is from 1885

 

I had an extra key copied for my 07 Elantra on Saturday. I locked my car
and armed it with the fob before I got the key copied, and I then opened the
door with the new key, to make sure it worked. The alarm did not go off.
