D4 unlocked by a Hyundai remote

As I have mentioned in another post - I used to work with Qantas Valet parking and on one very quiet day during the Christmas lull we took a bunch of keys to our secure parking area and tried pushing various "remotes" to see what would happen .... and sure enough we had quite a few cars "opened" by "other" keys ... as you mentioned some had "rolling" codes as we could only open the doors once and then it would lock us out ... we did this "experiment" as a result of various team members mentioning that they had "opened" two cars at a time occasional - I was sceptical at first but after a few "examples" I was convinced. We mentioned this phenomenon to a Merc dealer who was visiting and he said "it is a problem" but doesn't happen enough to worry about ... easily said if it's not your vehicle !!!!
cheers

I'll remember this next time I consider using Valet parking:)

The bloke across the road from my parents had to get his roller door code changed because it would lock his commodore every time he opened it. Pat

They can make computer WiFi devices have unique (MAC address) codes. It seems to me that the automotive manufacturers are just being cheap using out-dated technology.

On the other side of the coin, the improvement in automotive security has resulted in a reduction of vehicles being stolen off the street with a concurrent increase in the rate of car-jackings for the same purpose.

Don't know about you and I know how frustrating it can be when a car is stolen, but I'd rather it be stolen on the street that suffering the risk of injury in a car-jacking.

My nephew had a Stanley knife put to this throat
when driving home in Liverpool UK a couple of years back,
whilst stopped at a set of pedestrian-activated crossing lights.
ALWAYS lock your doors. He stepped out and the two guys
drove off in this mother's new Mini . It was abandoned 35miles
away in Manchester's less than pleasant neighbourhoods.

Yup !!

Several years ago I was o/s for a few months and ended up buy a Hyundai Getz 2nd hand to run around in. (Actually it cost me more than a new one here would have and I got it cheap there !!) Turns out that my neighbors vehicle was coded the same (different manufacturer).

It was actually quite easy to take my car down to the local dealer and borrow his obdii unit to recode my keys and ignition, took about 5 minutes per key (with checking).

Mind you next day had to go back and do it again, as I had set the code as a different neighbor across the street (ARG!!!!).

Thanks gps-au - I wondered about just recoding the keys. I have an MVS2 so will be checking if there's an option to recode the keys at the same time as making a few setting changes. The MVS2 doesn't show what it can do unless its connected to the PC and vehicle.

I once had to unlock my MkII Cortina with a wire coathanger (I'd locked the keys in).

Then, a few years later I had an XY wagon and I was able to use the same coathanger to unlock that car after a similar occurrence!:eek:

Amazing that they cars were coded the same so that the coathanger worked with both - except the cars were from ther same manufacturer. Bloody cheapskates at Ford who wouldn't invest in rolling code hangers!
