So I'm sitting down enjoying pre Thanksgiving festivities when my alarm sounds
I casually get up assuming that a gremlin is the culprit. Before I get outside the alarm stops. So when I put the key in the door nothing happens. As of now I can't open the doors or trunk. Does anyone have an idea of how I can get into the car?
(EDIT: with all that I said below...one must also consider if the car's battery's loss of voltage is due to a consistent state of discharge from age or time...or is it not being sufficiently recharged by the alternator...thus making it a victim of the charging system, instead of the overall culprit)
Since the car's alarm siren has a rechargeable battery incorporated into it's design...if the car's battery's voltage has dropped to the point that it can't keep up with all the car's electronic needs...the car can basically go thru a "rolling brown out".
Then if the alarm siren's battery voltage drops due to it's internal battery not being kept fully charged...it will take that drop as a sign that someone has cut power to the car and is trying to steal it.
So in some instances...a false alarm can be triggered by a drop in voltage from the car's battery. It's one of the things one should check (car battery) if faced with a rash of false alarms. Also take note if ONLY the alarm is sounding and the LIGHTS are NOT flashing...this is a good sign that the problem is more than likely the car's battery (since when the alarm is actually triggered under normal circumstances, the LIGHTs as well as the SIREN should be activated.
I use Autozone 49DL battery, very happy with it.
Search for equivalent battery from Walmart.
Autozone will price-match it.
Listed price is $94.
I paid $80.
You might want to check the battery specs. Some 49 class size batteries and possibly some of the newer H8 or H9 class size batteries may have better specs.
Remember to compare:
RC -reserve capacity
CA - cold cranking amps
CCA - cold cranking amps
The Duralast 49 DL may be the better buy over the Duralast Gold 95R...but again, check the specs and see which one works better for you.
