I know what you mean because the sister of this kid has a Camry 2005 with the immobilizer driving her nuts because it goes on constantly.
When I'm done helping with the 2004 Lancer, I may get her some remotes for her Camry and program them.
My even older bimmer does that.
Yup. These are older cars.
Yup. My bimmer has that per-key "seat memory" too.
Remember - you are NOT PROGRAMMING THE REMOTE. You are training the BCM - or "adding the remote" to the BCM
If a 3 button fob is available for the car, it will work. Personally I've never seen an OEM type fob with only 2 buttons, I'm sure they must exist, but I've never run across one. I think even most pickup trucks come with 3 button fobs (and some have power tailgate locks - -
-
The fob is NOT BEING PROGRAMMED. You can actually add the same fob to more than one car .At the same time. You are programming the CAR to the fob, not the other way around. Each fob has a unique identifier code, and each make and model of car can use a specific range of codes. Programming adds the identifier of the fob into the list of acceptable codes (if it falls into the range for that vehicle) in the car's body control module (computer)
That's interesting that the same fob can work on more than one vehicle!
Thanks for that clarification (I saw it in another post also). Much appreciated.
This one is two buttons, but I agree, the three button fob is the way to go!
.. I can just see it now - me - walking through the crowded parking lot - clicking away to see if I can open any cars . :-) John T.
I always wondered if the same key (in the olden days, we all had metal keys, remember?) would open more than one car...
It would have to have been programmed into the car - but I HAVE seen a remote unlock the wrong car - I guess there are only so many codes????
Definitely.
The key to my Dads 66 ChevyVan would open and start his brother's (who dad worked for at the time) 1958 Chevy 1 ton - and it also opened and started a Pontiac that someone parked in front of the loading bay. (he moved it to the far end of the industrial complex the shop was located in)
In Zambia 15 keys would start virtually every Peugeot 404 (and quite a few other peugeot models) in the country - so I put a FIAT ignition switch in my 204
My parents had a 1963 Chevy Impala and that key would unlock and start a friends Ols F85.
Three boys in high school each had a Fod Mustang. Fords had seperate ingition keys and trunk keys. Between the 3 cars, each one could be unlocked and started by finding the right combination of keys of the other cars.
I was looking for something else and I found this post, from a month ago, so you probably won't see my answer, and if you do, I probaably won't see yours. But my email address is good if you remove NONONO.
I too, with a 2005 Toyotal Solara had a problem that it only opened with the fob or the lever on the floor.
Now I had 2 good fobs, but because it's a convertible, I had to disable the lever on the floor. I guess the alarm would have gone off if they climbed over the door or the back and opened the trunk, but the alarm stops after a short time.
So if I'm out and the fob battery fails, no way to get into the trunk.
So I put in an electric switch, on the dash, that shoud have been there in the first place. It wasn't that easy. Couuldn't find the wire -- well maybe I could see it but I couldn't reach it -- without removing the left kickpanel and cutting into two different sheaths, looking for a white wire. There were two of them so I had to test which one worked. And I connected a push-button switch to that one and the cig lighter that is hot when the ignition is on.
I'm really glad I did this.
AFAIK, all have used pseudo random codes and the chance that any remote would open another car is probably lower odds than winning the mega millions lottery. Same thing with the newer garage door openers, made in the last 25 years or so. Old ones did have fixed codes set with dip switches.
I just saw something on the Genesis forum about that happening. I have a Genesis G80 also and our cars have a "smart trunk" that will open for you. Below is what this guy posted.
Walking through the parking lot at my daughters high school last Friday night during the first football game of the season and as I walked by a newer Toyota Sienna van the rear lift back started to raise and beep. As I walk further away it closed.
I didn?t think anything of it. Figured someone else was nearby with their fob or maybe in the van.
Walked by a while later and it did the same thing. So I walked up to it and sure enough it opened. As I walked away it closed. I played with it a few times.
Apparently on the same frequency as my G80.
Then you see that guy with the lap top walking along opening car doors and starting the cars.
It's inconceivable that they just base it on frequency. It seems beyond belief that they would base it on even a limited number of codes, because a thief could run through a bunch of codes with a computer or just capture the code you're transmitting and wait until you're gone and then use it to open it. But obviously something really dumb and bad is going on. IDK who you'd complain to, because it wasn't your car that opened by mistake.
