Hello Kimberly 210,
I looked up your ignition to assure MYSELF your
key ... is indeed a standard
TRANSPONDER.
(no idea what country we are talking about...??)
That type of response SEEMS to be a
SECURITY
response... As though
ONE of your keys is in trouble...
(
TRANSPONDER KEYS can be damaged & intermittent) ...
My best advice is to get on eBay and find yourself
a COUPLE of NEW uncut OEM key replacements...
Shop around and find out if you have a cooperating
locksmith who will cut and code the keys for you...
The BEST price I've paid was $6 per key cut...
The worst was $60..
(they ruined my OEM key and sold me a generic
(I felt it was deliberate.. my OPINION)).
IN ANY CASE: If you wait until the key goes bad a DEALER CAN GET (page 120, 3-10 owners manual)
from $300 to $600 for full key service
AND that
IS
NOT INCLUDING the
tow charges.
Some cars allow you (the owner (nothing found))
to code the keys yourself...
but you CANNOT do it WITHOUT at least
TWO (2)
WORKING KEYS...
Sorry... I don't know TIBURON specifics
