How to Protect Yourself from Car Theft
Car alarms and antitheft devices are great, but you want to make sure you have the obvious things covered first. Here are some tips for protecting yourself from car theft:
Always lock your car when you get out and take your keys with you, even if you're planning on being inside a short time.
Park in well-lit public areas.
If possible, park in a garage at night or at least off the street.
Don't leave valuables in your car (or hide them in the trunk if necessary).
Keep a copy of your title and vehicle registration at home. Know your license plate number, or write it down somewhere. You need this information if your car is ever stolen.
Don't leave spare keys anywhere on your car. You can keep a spare key in your wallet if you have a habit of locking yourself out.
