Chevrolet Repair: tpms, gm cars, lt 2

Question
wife has 2008 cobalt lt 2.2 liter...she left lights on killed battery..now tpms doesn't read tire pressure..when i follow directions to relearn using method for vehicle without key remote there is no option to select tire learn from menu..is there another way to relearn tire pressure without key or do i have to get key with remote?  when we bought car used we were given a key without remote

Answer
HI RON,HAVE YOU TRIED DRIVING THE CAR FOR A FEW MILES FIRST BEFORE DOING A RELEARN,IF NOT, DO SO FIRST.. THERE REALLY IS NO REASON WHY THIS SHOULD NOT OF RELEARNED THIS WHEN DRIVING A FEW MILES AFTER JUMP STARTING OR NEW BATTERY INSTALLED.  TO ANSWER YOUR QUESTION IF YOU HAD A GM SCAN TOOL OR TPM SCAN TOOL YOU COULD RELEARN THE SYSTEM WITH THE SCAN TOOL. BUT AGAIN THIS SHOULD NOT OF HAPPEDNED WITH A DEAD BATTERY. MAY HAVE A BAD TPM MODULE. MOST GM CARS REQUIRE A REMOTE TO LEARN IF YOU DO NOT HAVE THE SCAN TOOL..SO TO SUM THIS UP >> IF AFTER YOU DRIVE THIS AND RELEARN DOES NOT SET,TAKE THIS TO A SHOP THAT HAS A TPM SCAN TOOL AND HAVE THEM RELEARN THE SYSTEM..IF THIS DOES NOT WORK MORE THEN LIKELY THE MODULE IS BAD. WHAT MAY OF HAPPENED IS THE MODULE COULD OF RECEIVED A SPIKE FROM JUMPING THE BATTERY,,,JUST A GUESS, BUT WE HAVE SEEN THIS HAPPEN..YOU DID NOT CROSS THE CABLES WHEN JUMPING DID YOU ??? JUST ASKING.. I HOPE THIS INFO HELPS YOU,,,TOM.
