The security, antitheft or lock picture/icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.

That was a reset, try a relearn. You'll need a charger on the battery. Ten minutes on, thirty seconds off. Do this three times, then try to start. If that doesn't work, then it has to go on a scanner to see what happened. Sparks like yours usually don't hurt anything. But they can spike and burn a computer. Next time put the positive side on first.

You could have a parasitic drain. Something that is left on in the car and drains the battery. It could also be a corroded terminal on the battery where the alternator is not getting power to charge the battery . Clean the post and the connector of all deposits and install those felt washers under the terminals to impede further corrosion.

You need to do a hard reset of your clock. On the touchscreen, select "MENU", when the screen changes, touch the lower left corner and hold until the PIN screen appears. Now enter the PIN code 295660, touch "NEXT", "PAGE", then "SET TIME".

You need to get down lower. I had to tear apart the dash to get to the lower air duct where a piece of candy was rolling back and forth.

The wires could be shorting or have a bad connection any where in the length from the radio to the sub woofer. I lost all sound in my Tahoe and thought that the connection was at the radio but never found a problem. One day on a hard left turn a loose chair in the back area of the Tahoe struck the right side panel which has the speaker and everything starter working.

Under the hood in the power distribution/fuse box, it's on the driver's side between the firewall and the battery! Thanks and have a great day!

Tow/haul mode enables the operator to achieve enhanced shift performance when towing or hauling a load. When tow/haul mode is selected, the tow/haul switch input signal to the body control module (BCM) is momentarily toggled to zero volts. This signals the powertrain control module (PCM) to extend the length of time between upshifts and increase transmission line pressure. Cycling the tow/haul switch again disables tow/haul mode and returns the transmission to a normal shift pattern.

Would't trust it , take an have DTC'S - diagnostic trouble codes checked by a qualified repair shop with a factory or professional scan tool . Auto part stores can not check BCM code's .
DTC B2722

Tow/Haul Switch/Indicator Always On or Inoperative

Install a Scan Tool .
Turn ON the ignition, with the engine OFF.
Cycle the tow/haul switch while observing Tow/Haul Mode on the Scan Tool .
Does the Scan Tool display Active when the switch is first pressed, and then Inactive when the switch is pressed again?
Go to Intermittent Conditions in Engine Controls - 4.3 L or Intermittent Conditions in Engine Controls - 4.8 L, 5.3 L and 6.0 L

Most likely the throttle position sensor. I would start by cleaning your mass air flow sensor and throttle body. Go on google or youtube and search it and watch a video on how to propperly do it. You may find a video on your exact vehicle and problem if you put the info in the search.
