Ford Sharp detailed tutorial on replacing remote key battery
NoviaNorris 
7 Ford Ruijie 2.7 Sports Edition has been bought for five years, and the remote control key battery has not been replaced. Not long ago, I was thinking about this. In the morning, when I was going to work yesterday morning, the computer suddenly popped up a window, reminding me that the power of the key was low. I need to replace the key battery.
At work, the computer system of the display screen automatically pops up a message showing that the battery of the key is low, indicating that we need to replace it immediately.
For five years, the key battery has not been replaced, and it is estimated that it is almost done. The message on the display screen is clear.
Immediately began to place an order in SUNING, bought a version of Cr2025 car key special button battery, can only buy one version, can not buy two.
This is the full page of the five Panasonic cr2025 upon arrival.
According to the battery information on the back of the full page, the Ford sharp boundary original car uses two Panasonic cr2025 batteries.
Take down two 2025 and get ready to replace them.
Take out the Ruijie original car remote control key that you take with you. The leather cover is the same as the leather case bought a few years ago. The leather case is a little dirty, but it is very clean to protect the original car key as new.
After opening the coat, it looks like a brand-new remote control key.
The complete key, the back, the tail top is the clasp, want to remove the shell, must use the hand to press the clasp lock, press hard, you can directly remove the key shell.
This is the remote control key after removing the shell. Inside is a sharp mechanical key, the function of this key is that if the car has no electricity to open the door, you can use this key to enter the driver’s door.
Take off the mechanical key and prepare a fifty-cent coin. remember that you must have a fifty-cent coin. some cyclists use one yuan, and the torque of one yuan is too large. when you push hard on both sides, it is easy not to break the inner buckle of the inner and outer layers. The torque of the five-cent coin is just right. Hold the coin and a little force at both ends, you can separate the upper and lower layers.
This is the exact position where the fifty-cent coin is inserted into the upper and lower layers. Squeeze the sides of the coin a little harder to separate the inner and outer layers of the key.
This is the internal structure diagram after separating the inner and outer layers of the key. note that there is a layer of sticky substance on the negative surface of the sharp key battery. It has been proved by many parties that it is a layer of conductive paste, not battery leakage, which is easy to be misunderstood. Of course, this layer of sticky conductive paste can also be wiped clean. No, no, no.
Prepare a small tweezer for battery use
Carefully removing the upper battery with tweezers, the Ford Sharp remote key requires a total of two cr2025 batteries, divided into two layers, with a piece of insulating paper in the middle. As shown in the picture, the upper battery is removed. It is hereby explained that the sticky material on the battery is a conductive paste, not a leakage. We must pay attention to it. At first, I thought it was a leak, but in fact, it was not. There were all negative electrodes on every key battery. Later, I asked Ford headquarters that the conductive paste could be wiped clean. It is mainly to delay the discharge, but it does not have much practical effect.
Remove the insulating paper in the middle. Expose another cr2025 battery in the lower layer.
Remove the lower layer of the battery with tweezers and find that there is also conductive paste on the negative electrode of the lower layer of the battery. And there is a lot of conductive paste on the plastic board under the battery.
Two batteries coated with conductive paste and a close-up of plastic.
Even there is a lot of conductive paste around the battery contact point on the circuit board.
A close-up of a battery coated with conductive paste. Then wipe the conductive paste on the circuit board and plastic board with a clean napkin to avoid getting sticky and looking less comfortable and clean after changing the battery.
Replace the new battery according to the original step, make sure that the positive and negative poles don’t get it wrong, and move the insulating paper back to the middle.
Replace the inner and outer layer of the new battery, first put the outer part of the ear into it, and the side of the clasp immediately cocks up.
This is the part of the ear that was put in first.
Press the ear with your hand, press the snap end hard with the other hand, and hear a click, indicating that the two ends of the snap end have completed the inner and outer fit.
Install the inner and outer key as a whole.
Put in the mechanical key and return to its original position.
Cover the back of the key, advance the head, and finally press the end of the bayonet.
The picture after all is finished.
All the tools need is a small tweezer and a five-cent coin.
After the completion of the sharp boundary of the original car keys replaced with new keys.
In fact, the replacement of Ruijie remote control key is a very simple thing, as long as you are willing to do it, there is no need to bother others at all, everyone can have hands-on practice, as long as you can fully master it once, have you learned it, fellow cyclists?
