Took off meta alarm now wont start

the guy pushed a button under my dash turned the key and car started

you need to know where that push button is under the dash

if you cant find it your self ... ring the place back for instructions

not nice but
you may have to get them to call out and show you or
tow the car back to where you got the battery fitted

1 Turn the ignition key counter clockwise in the driver's side door to unlock the car. This deactivates the alarm long enough for you to gain access to the vehicle. Then, place the key in the ignition and turn the key until it clicks once. This starts the car's battery, but doesn't ignite the engine. The LED light on the dashboard should stop blinking, indicating the alarm is temporarily disabled.

2 Locate the box for the alarm under the dashboard on the driver's side of the car. Then, look for the override button on the box. Typically, the small button is either red or black. With the ignition key in the "on" position, press the override button and hold it in until the alarm chirps once. This disables the alarm until you manually reactivate it.

3 To reactivate the alarm, turn the key to the "on" position and press the override button once. The alarm chirps twice, indicating the alarm is active.

Hope this helps!

some of those cars have a fuel reset button see if your car has that and give it a try

Hello there, I have a problem with my Piaggio X9 500, 2002 model dashboard. When I turn the key on, the injection, alarm, rear brake, gas reserve, low and high beam bulbs do not check initially , thought they work fine after when I press each button. Could you please give me any suggestion? (the dashboard clocks are NEW!)

my code alarm remote don't work? what is the solution for this?

It's immobilized (won't let you start the engine) or won't immobilize now?
If locke your engine then try turn key on, press start to do a short crank, let go for 3 times cycle then on 4th let it start as normal.
Have you checked your meta M357 Alarm user manual for owner unlock sequence?

the jetta has a faulty alarm system from the factory i have been working on one in my shop. the alarm moddule is inside the dash behind the light switch and has a 10 pin connector and a 6 pin connector. this can be bypassed if you disconnect both connectors and jump the two large wire on the 6 pin connectors, these wires operate your starter. the car will start and run but your alarm will no longer be active. the door locks and everthing else will still work. the only issue i am having is the factory radio isn't working because it is controlled by the alarm. but worse case scenario i can use an aftermarket radio if need be.

Your GM product has a safety alarm, it shuts down the radio , or locks it.
I send ours to a GM dealer to get it unlocked. They don't give those codes out.

'99 camry: with alarm sounding. turn key to "ON" position and press in and hold alarm button (red two position (in /out) on dash board. Button should go from flashing red to solid red. Release button when it stays lit (solid bright red) . Alarm is now in disabled mode and engine should crank when key is turned to "start" position.
