Saab Key Programming

Saab cars built since about 1994 have an immobilizer system built on coded keys. A new transponder is required for the addition of an additional key, as well as special programming. This is usually done by the dealer using a special Tech2 diagnostic tool.

It can be costly. This is why you should always keep a spare key in your possession.

Transponder key

The transponder is a type of key that is equipped with an electronic chip. This chip sends out a signal when the key is inserted into the ignition. The car then checks the signal to see if it matches the one that is in the key. If both signals match the car will be able to unlock itself and begin. This is an excellent way to protect your vehicle from theft.

Transponder keys can be an increasingly popular feature for cars, but they're not as secure as traditional metal keys. The metal component of a traditional key is easily cut and copied, whereas the transponder is protected by an electronic chip that protects it. This chip contains an unique code which is programmed into a car's computer order to identify it.

When a Saab key fob is used the car recognizes it and allows it to turn on. But, Saab 9 3 Key Replacement it's only able to do so if the key fob is equipped with a chip that is not modified that has been programmed to match the original. In the absence of that, the car will refuse to accept the key and will not start.

It is vital to have a spare Saab key. This is particularly important if you reside in a rural area that is home to numerous car thieves. You can get a brand new key for your Saab by going to the dealership, without having to pay their pricey costs. In most instances, you can get a new key created on-the-spot for less than half the price of what you would pay at a dealer.

Key for Wired

Saab cars are usually provided with two keys. If you only have one, it's best to acquire an additional key fob as soon as possible since if you lose it the car will require the replacement key for saab 93 of a CIM unit, and the locking cylinders will need to be replaced. This can be costly particularly if you are buying a second-hand car.

The next step is to connect the column and row wires to the microcontroller. This is the most challenging part of the project and will require a good amount of soldering. It's not a common way to go about it, but you must plan How to program saab 9-3 key fob to connect and Repair solder each column and row. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins to connect.

Once the rows and columns are soldered, it's the time to connect them to key switches. To do this, put a diode on each pin on the key switch and then solder it. This will shield the pins that are used for key switches from current and also prevent them from being shorted. A diode lets current only flow in only one direction. It comes with a visual indicator, a black band, that shows the direction in which the current will flow.

Some of the tools available at auto parts stores -- such as the Autel MaxiIM IM608 Pro and IM508 -- could help shop customers or even DIY users in some cases replace keys in the program and restore lost immobilizer data, Sanabria says. The tools plug into OBD ports and guide the customer through each step making the process simpler than replacing the vehicle's computer.

Jump starting the battery

A lot of people keep a set of jumper cables in their trunk to use in an emergency however, jumping a battery in newer vehicles might not be the best option. These vehicles are equipped with digital and computer systems that communicate with one another. A surge in voltage while the battery is connected to another can fry these components, rendering your car unable to drive.

Connect the cables to the vehicle that is operating. Let it run for two minutes. Attach the red clip on the positive terminal of the good battery. (It will say "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface under the disabled car's hood. The engine block is an ideal choice. The black cable is not to be connected to the negative terminal of the dead battery. This could create sparks that could ignite the gasoline inside the engine compartment.

After the cables have been connected, you need to start the car and let it run for about five minutes. Then, disconnect them in reverse. Remember that the battery on the saab 9-5 key replacement 9-3 will be charged when you drive, so it can take a while for the battery to come back to normal. It's a good idea to invest in a spare key fob as soon as you can, since replacing the only working one requires the installation of a new computer module and special programming to convince it that your missing keys are not trying to steal the car.

Replacement Case

Many saab 93 key programming owners have only one key for their vehicle and if they lose it, the cost will be. The reason for this is that it's not cheap to buy a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. It's recommended to have a spare key in case of theft or other disaster, and the best way is to buy an extra key as early as you can. Don't purchase a used key even if it's "new." Claimed-new keys from a second-hand store will not be effective and are almost guaranteed how to get a saab replacement key fail at the critical moment.

The dealer will charge you the most expensive dollars if you only have one working key. We can reset and reprogram the EEEPROM of your computer to be able to accept a new key without replacing the entire system. This could save you a great deal of money. It's also less expensive than waiting until you lose your sole key.
