How To Lock Your Car

[dbhost]

I wondered about the security code of remote keys.

Something similar: Last week I went to an acquaintance's house in my 2004 Toyota van. I parked beside his 2006 Toyota Van. He was going to show me some places to visit in his town when my family comes from the US (Tomorrow). After returning to his house from the tour, I went to get into my van and I clicked the button to unlock. His van unlocked too. He clicked lock from his remote, and mine locked too. I clicked unlock and his unlocked also.

These remotes here are a single button type. Press once and if it is unlocked, it will lock; if it is locked, it will unlock.

What are the odds of parking beside a vehicle with the same code as yours?

Both from Toyota? Pretty good actually... I had a 1976 Toyota Celica, my ex had a 1981 Celica. They had the EXACT same key. I'd imagine codes aren't much different from keys...

This issue with remotes and security systems is nothing new at all... Code sniffers have been around since the late 1980s, security system companies are constantly coming up with new technologies to combat them, but the crooks usually seem to have the upper hand...

If you have a car alarm, the same thing is true there. The remote code can be sniffed, and used to unlock / disarm the alarm... This has been the case for 20+ years now... Sorry if you didn't know.
