saab 9-3 key not accepted contact service Key Programming

Saab cars built since about 1994 have an immobilizer feature built on coded keys. In order to add a second key, it requires an entirely new transponder and programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool.

The problem is that it can be extremely expensive. It is always advisable to keep an extra set of keys at hand.

Transponder key

The transponder is a key with an electronic chip. This chip sends a signal when the key is placed in the ignition. The car is able to check if the signal matches the one on the key. If the signals are in sync the car will then open and start. This is a great method to avoid car theft and keep your vehicle safe from thieves.

Transponder keys can be an increasingly popular feature for automobiles, but they are not as safe as traditional keys made of metal. The metal part of the traditional key can be easily cut and copied, however the transponder is protected by an electronic chip that protects it. The chip is equipped with an unique code that is programmed into the car's computer to identify it.

The car will recognize the saab ignition key Replacement keyfob and permit it to turn on. However, it can only do so if the key fob is equipped with a chip that is not modified that has been programmed to match the original. The car will not start in the event that the key is not programmed to match.

It is vital to have an extra saab 93 replacement key key. This is particularly true when you live in a rural area that is home to many car thieves. The good thing is that you can obtain a replacement key for your saab replacement key without having to go to an auto dealership and pay the expensive prices that they ask. In the majority of cases, you can have a new key created on-the-spot at a fraction of the cost you would pay at dealerships.

Wired key

Saab cars are usually provided with two keys. If you own only one, you need to 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 could be expensive especially if buying a second-hand car.

The next step is to connect the wires of the column and row to the microcontroller. This is the most challenging part of the project and will require a good deal of soldering. There's no standard way to accomplish this, but it is crucial to plan the route you'll take and solder the columns and rows. There are 22 microcontroller wires as well as pins to connect to this keyboard. It has 5 rows and 17 columns.

After the columns and rows are soldered, it's the time to connect them to the key switches. To do this you must place a diode on each pin on the key switch and solder it. This will shield the key switch pins from current and stop them from being shorted. A diode lets current only flow in only one direction. It has a visual indicator of a black line that indicates the direction in which current will flow.

Sanabria states that a number of the tools offered in auto parts stores, like the Autel MaxiIM IMM608PRO and IM508, can help customers shopping or DIY users to program replacement keys and restore the immobilizer's data. The tools plug into the OBD port and guide the customer through the procedure, making it simpler than replacing the computer inside the vehicle.

Jumpstarting the battery

A majority of people keep a set in their trunks to start a car in an emergency, but it might not be the best idea for newer cars. These vehicles are equipped with numerous digital and computers that communicate with each other. A surge in voltage when the battery is connected to another can fry the components and render your vehicle unusable.

Connect the cables to the vehicle that is operating. Allow it to 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 of the black cable to a clean, unpainted metal surface under the disabled car's hood--the engine block is an ideal choice. Do not connect the black cable to the negative terminal of the dead battery, since it could ignite an ignition source that ignites gasoline in the engine bay.

Once the cables are connected, begin the car and let it run for approximately five minutes. Then, disconnect them in reverse. Remember that the battery on the saab 93 key 9-3 gets recharged when you drive, and it can take a while to get the battery back to its original level. You should invest in another key fob as soon as possible. Replacing the only one that works requires the installation and programming of a new computer chip.

Replacement Case

saab key replacement owners usually have only one car key, and if it is lost, they will be charged. It's expensive to buy keys and will require replacing the CIM or TWICE for older models. In the event of theft, or any other disaster it is best to have an extra key. But don't buy a used key even the case that it's "new." Keys that are claimed to be new from sellers selling aftermarket keys won't work and are likely to fail at the critical moment.

The dealer will charge you top dollars if you only have one working key. We can, however, reset and reprogram the computer's EEPROM to accept the new key without having to replace the whole system. That can help you save money. It's less expensive than wait until you loose the only key.
