Does Leaving The Car Unlocked Drains The Battery ?

[prashanthchou]

I had recently purchased a used car - Lexus ES300 -2002 model.

Its been 3 months.

Usually I park my car in closed garage and usually do not care to lock it.

Just wanted to know if leaving the car unlocked drains the battery ?

Why would you think that? Locked or unlocked, there's no change. The draw on the battery from the security indicator would actually suggest leaving it locked creates more of a drain, but the amount is so negligible it would take months of sitting to effect the charging system.

I was thinking the same thing...locking the car arms the alarm...so what would leaving the car unlocked do?
