Question about 2003 Buick Rendezvous

1 Answer

How do I reprogam keys for my 03 Buick Rondezvous. We lost a key a few years ago and last year bought a new key (to have a spare). The car dealership had said that I needed to bring both keys & vehicle in to program everything. Just found old lost key, stuck it in the ignition, now car will not start with either keys. Help!!

Insert key and turn ignition to on position. Wait untill the "security" light goes out (about ten minutes). Turn key off. do not remove. repeat this step two more times. After third time remove key. You should now be able to start vehicle. To program the spare use the already programed key and turn it to the on possition (dont start) then off. remove key and insert spare and turn to the on position. Wait for "security light to go out then turn key off. Both keys should now be programmed.

2 pods and 1 full,
my 04 (sold) GV, only one key can be programmed at a time.
but has no IMMO on car, only the door locks are dead on my spare.
the operators guide (lost that?) tells you how to get the fob programmed all by your self.
the key , any lock smith in earth can cut you a new one.
but house calls or road trips are more money. to cure that.

GV are sold all over the world. 1999 to now.

I have lost the electronic key, are you able to start the car with the manual spare?

no year or car stated, wow!
if you car has the immobilizer, it will never start until that module
is happy (light out)
so, what is your question.?
the operators guide answers these simple questions. did you lose that?
on my new car,the key is RFID and must be good.
the metal key works in door's only, to save the baby for not drive.
see>? ( no year stated so.... no accurate answers ever)
if the manual is lost read it it for 4 bucks here.
i guess you lost the 2nd key too, that came with the new car
that too, is the 1st question to ask with all IMMO cars. see why?
answer , not stranded, have 2 keys. WIN.
answer 2, you can make a 3 key by self, with 2.
see? (or as directed by your unstated year, oper, guide,read it first)

click owners manuals here... and....

what year
what car

How do I get a replacement key for my 1998 buick Century

I have the same problem with the same model year buick,since i lost the door key and can only lock it electronically. Not sure how long it will last,or what would happen if the "beeper" button stopped working? Anyway,think it's a GOOD idea to obtain a new key just in case. Will look into it when i get the chance.

Key wont unlock door suzuki grand vitara

Not a car expert but have some common sense advice---is it possible the vehicle was re-keyed before you got it? Someone may have lost the original keys and resorted to just using the other feature---a year is a long time not to know about this---I should not talk as recently got a vehicle where owner said rear window would not open for last two years=that vehicle has child safety locks on rear doors that also disable windows--needless to say nothing wrong.

I would talk to Suzuki if the key box is a factory installed item to see if it has a way of locking the physical keys out.

Worth asking---if after market item it may have been installed in a way that causes this issue.

Key will not go into the ignition buick rendezvous

Had this happen to me on a 2004 Rondezvous on 1-18-13. I was lucky enough to find this answer that worked like a charm by Buckeye L ----

This is a VERY common problem. There is a flat brass wafer that has dropped inside the ignition. take a file or something very flat and gently insert it into the keyway and gently move it up and down all the way down the keyway.
This should move the wafer to allow the use of the key. However, the cylinder needs serviced and will do this again.
It seems to be a manufacturing issue on these vehicles that use these modular ignitions.
Never use graphite as this usually compounds the problem based upon our experience.
