saab ignition key replacement Key Programming

saab 9-3 replacement key cars that were built prior to 1994 feature an immobilizer mechanism based on coded keys. The addition of a key requires a new transponder and special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

The problem is that it can be very costly. This is why it is important to always have a spare key at hand.

Transponder key

The transponder can be described as a key that has an electronic chip. This chip sends a signal when the key is inserted into the ignition. The car then analyzes the signal to see whether it is identical to the one that is in the key. If the signals are in sync it will open and start. This is a great method to prevent car theft and keep your car safe from thieves.

Transponder keys are an increasingly popular feature in cars, but it is important to know that they're not as secure as traditional keys made of metal. The metal part of the traditional keys can be easily cut and copied, whereas a transponder has an electronic chip which protects it. The chip contains a unique code that is inserted into the car's computer in order to identify it.

When a saab 9-3 key replacement key fob is used the car recognizes it and allows it to turn on. The car can only recognize the key fob when it has an unmodified chip and has been programmed to match. If not, the car will reject the key and refuse to start.

It is important to have an extra saab 93 replacement key key. This is especially important for those who live in a rural location that has numerous car thieves. The good news is that you can find a new key for your saab keys without needing to visit an auto dealership and pay the high costs that they demand. You can have the replacement key on the spot for less than half of the price you'd spend at the dealership.

Wired key

Saab cars are usually delivered with two keys. If you own only one, you should purchase an extra key as soon as you can. This is because, if it's lost and the car needs a new CIM and the locking cylinders replaced. This can be expensive especially for cars that are used.

The next step is to wire the row and column wires to the microcontroller. This is the most difficult part of the project and will require a great amount of soldering. It's not a standard way to do it, but you need to think about how to route and connect each column and row. For this keyboard, there are 5 rows and 17 columns. This means there will be 22 microcontroller wires and pins to connect.

After the columns and rows are soldered, it's time to connect them to key switches. To do this, you need to place a diode on each key switch pin and then solder it. This will protect the pins of the key switch from current and also prevent them from being shorted. A diode can only allow the flow of current to be in one direction, and it comes with a a black band visual indicator that indicates the direction in which current will flow.

Some of the tools you can find at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- could help shop customers or even DIY customers in certain instances replace keys in the program and restore lost immobilizer data, Sanabria says. The tools connect to OBD ports and guide the customer through each step making the process simpler than replacing the car's computer.

Jump-starting the battery

A lot of people keep an assortment of tools in their trunk to jump-start a vehicle in an emergency, but this might not be a good idea for newer cars. These vehicles are equipped with a number of electronic devices and computers that communicate with one another. A voltage spike when batteries are connected to another one could cause damage to the parts making your car unusable.

Connect the cables to the vehicle working. Let it run for two minutes. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end to a clean, unpainted metal surface beneath the hood of the affected vehicle. The engine block is an excellent alternative. Do not connect the black cable to the negative terminal on the dead battery as it could spark an ignition spark that ignites the gasoline in the engine bay.

After the cables have been connected, you need to begin the car and let it run for about five minutes. Then disconnect them in reverse. The battery in your saab keys replacement 9-3 will be recharged while you drive. It will take some time for it to return to its original state. It is a good idea to buy a spare key fob as soon as you can, because replacing the sole working one requires the installation of a brand new computer module and special programming to convince it that the lost keys aren't attempting to steal the car.

Replacement Case

Many Saab owners only have one key for their car and if they lose it, they'll be charged. It's expensive to purchase the key and also requires replacing the CIM or TWICE for older models. In the event of theft or any other calamity, it is best to have an extra key. Don't buy a secondhand key, even the case that it's "new." Keys that are claimed as new from aftermarket sellers will not perform and are almost certain to fail at the crucial moment.

The dealer will charge the highest dollar for only one working key. We can, however, reset and re-program your computer's EEPROM to prepare it to accept a new key without replacing the entire system. That can help you save money. It's less expensive than wait until you loose the only key.
