Tip & How-To about BMW 535

Have you ever locked your car keys inside the car?

Well the solution come here : (this may work for all type of cars)

If you have remote control car lock system in your keychain (Very Common These Days), you are saved !

Just call some one at home at his/her cell phone and ask for the duplicate keys to someone at home.
Now, as usual the key chain of duplicate key would also be having the remote control, so ask the person at home to press the unlock key on the remote.
While the person press the unlock key hold your mobile phone about a 10-12 inches from the car door.
The unlock signal will travel on the cell phone network and your car will be unlocked !

Note: On some networks the trick may not work!

how do you change the battery in the remote key chain?

Use a small flat screw driver to pry apart the 2 haves of the remote transmitter. When you have it apart check to see if the battery hold down is soldered in place, very common for it to come apart.

car unlocked but it sets the alarm ... car locked alarm goes for no obvious reason s type 4 liter.

Are you using the the keychain to lock unlock the vehicle? A low battery in the keychain will send wacky codes to your vehicle alarm system and will not set properly. Try using the key in the door to lock unlock vehicle. IF the alrm does not go off when using the key in the door, then you probably have to change the battery in the key chain. Best guess without being there to look at vheicle.

2000 chevy blazer security system making doors lock and horn blow while driving. Also wont start when less than a quarter tank of gas. Just had the fuel pressure regulator cahnged less than two months ago. what could it be?

Possible malfunctioning remote control or receiver. Try removing the battery from your remote (keep it handy) or take the #2 remote instead to see if the problem persists. Right now, it could be in either one of two places. Another thought; if you have never replaced the battery in your keychain remote, it may be overdue; 13 years is even way past the 'shelf-life' of these.
