They expect 4 to 8 inches north and west of Philly, 2 to 4 inches in the city and (hopefully) just a dusting here at the shore, maybe all rain. Frankie
These pics are of the circuit board inside the key. This key has a transponder which tells the car (325Ci, BMW) it is the key that belongs to the car and to allow it to start the car. Without this key, the starter and fuel pump won't work. In the second pic, you can see two metal clips that are normally soldered to the board. One clip touches the + side of the battery and the other clip touches the - side to the battery. These clips broke off the board. I tried to solder them back on and failed. I then took a 2 hour tutorial on soldering on line and found out just how much I didn't know about soldering. You can see in the first pic where the battery goes. If you notice the batteries, one, that has the plastic around the edge, is rechargeable. I didn't know they made small ones like this rechargeable. I had a new one (3v) that wasn't rechargeable. But I decided to special order online the Panasonic rechargeable as long as I was going through all this work. Might as well put the right one in. I'll try to do a proper job soldering this time. If it doesn't work, I've only lost the price of the new battery. They want about $150.00 for a new key at BMW. I checked online for one and there is none. Also, this key recharges as you drive. Makes you wonder what you do if the battery goes dead. You can't start the car to recharge it. I read that you can place the key on top of an electric tooth brush recharger. It's supposed to work on the same principal. I wish I had known this BEFORE I cut the key apart to get to the inside. Frankie
