This may be a bit more of a rambling, but I used to have a '98 3.0 CL and it made its way through my dad, me, and my brother before we traded it in at about 200k miles after it had some expensive transmission issues.

One day I went back to the parking lot I had left it in and got inside, only to see a bunch of stuff in the car that wasn't mine, and all my radio presets had been changed. Several minutes later I had put it together that this wasn't my car, but a nearly identical CL.

At that point I got out and tracked down my own car, but my key unlocked this other CL without any problems...has anything like this happened to anyone else?? I just thought it was weird as all, and wondering how many folks out there have keys that'll unlock my car haha

 

I always use my keyless remote

 

I doubt it would have started because of the immobilizer, but yeah it's fairly common with older cars to have that happen, they only make so many keys. My friends key for his Integra used to open my other friends Prelude haha.

 

The honda lock cylinders are pretty similar, I know my key looks identical to an accord key

 

my keyfob opens my dads 98 accord so the remotes do have some of the same programing to

 

The CL's and accords share the same remotes and FCC frequency

 

Lol this is all bad!
