saab key replacement Key Programming

Saab cars produced since 1994 feature an immobilizer that relies on key codes. In order to add a second key, it requires a new transponder and special programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool.

The problem is that it can be very costly. You should always keep a spare set of keys available.

Transponder key

The transponder is a type of key equipped with an electronic chip. This chip sends out a signal when the key is placed in the ignition. The car then analyzes the signal to see whether it is identical to that of the key. If the signals are identical it will open itself and begin. This is a great way to deter car theft and keep your vehicle safe from thieves.

Transponder keys are a popular feature in vehicles, but you must be aware that they are not as secure as traditional metal keys. While the metal component of a traditional key may be cut and copied, a transponder is protected by an electronic chip. This chip has an individual code that is encoded into the car's system to identify it.

When a saab key replacement Key code, center1339.com, key fob is used the car recognizes it and allows it to turn on. However, it can only do this if your key fob is unmodified and has a chip that has been programmed to match it. In the absence of that, the car will reject the key and refuse to start.

It's crucial to ensure that you have a spare key for your Saab. This is especially important if you reside in a rural location that has many car thieves. You can obtain a replacement key for your Saab by going to the dealership, without having to pay their pricey prices. You can have the replacement key on the spot for less than half the cost you would spend at the dealership.

Wired key

saab 9 3 key replacement cars are usually provided with two keys. If you own only one, you should purchase an additional key as quickly as you can. This is because, if it's lost and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This can be costly especially for used vehicles.

The next step is to connect the row and columns wires to your microcontroller. This is the most tedious part of the project, and will require lots of soldering. There is no standard method to accomplish this, however it is important to think about the way you'll route and solder the columns and rows. For this keyboard, there are five rows and 17 columns. This means there will be 22 microcontroller pins and wires to connect.

After the rows and column are soldered together after which it is time to connect the key switches. Solder a diode to each key switch pin. This will shield the pins on the key switch from current and prevent them from being shorted. A diode only allows current to flow in one direction, and has a the black band as a visual indicator that indicates which way the current will flow.

Some of the tools you can find at auto parts stores -- such as the Autel MaxiIM IM608 Pro and IM508 -- may help customers in the shop, or even DIY customers in some cases create replacement keys and restore lost immobilizer data, Sanabria says. The tools plug into OBD ports and help the customer through each step which makes the process much easier than replacing the vehicle's computer.

Jump-starting the battery

A lot of people keep a set in their trunks to jump-start their car in an emergency, but this might not be a good option for vehicles with newer technology. These vehicles are equipped with a number of digital and computer systems that communicate with each other. A surge in voltage when the battery is connected to another one could cause damage to the parts, rendering your car undriveable.

Start the working vehicle and let it run for about two minutes before you connect the cables to the disabled one. Attach the red clip to the positive terminal of the battery that is good (it will have "POS" or "+" on it). Attach the other end of the black cable to a clean, unpainted metal surface underneath the car's hood. The engine block would be an excellent choice. The black cable should not be connected to the negative terminal of the dead battery. This could cause sparks, which could ignite the gasoline inside the engine compartment.

Once the cables are connected, start the vehicle and let it run about five minutes. Then disconnect them in reverse. Keep in mind that the battery on your Saab 9-3 is charged when you drive, so it could take a while for the battery to go down. You should purchase an additional key fob when you can. Replacing the only one that works requires the installation and programming of a new computer chip.

Replacement Case

Many saab 9-3 key programming owners only have one key for their vehicle and if they lose that it's going to cost them. It's expensive to purchase keys and will require replacing the CIM or TWICE for older models. It's best to have a backup key in the event of theft or any other catastrophe, and the best way is to buy an extra key as early as you can. Don't buy a secondhand key, even if it's "new." Keys that are claimed as new purchased from third-party sellers won't work and are likely to fail in the crucial moment.

The dealer will charge you the most expensive dollar if you have only one working key. However, we can reset and re-program the computer's EEPROM to accept a new key without replacing the entire system. This could save you a significant amount of money. It's also a lot cheaper than waiting until you lose the only key.
