Saab Key Programming

Saab cars manufactured from 1994 have an immobilizer system that is based on a set of keys. A new transponder is required for the addition of an extra key, as well as special programming. This is usually done at the dealer using a Tech2 diagnostic tool.

The issue is that it can be very costly. You should always keep a spare set of keys in your possession.

Transponder key

The transponder is a piece of key that has an electronic chip. This chip sends out a signal when the key is placed into the ignition. The car then checks the signal to determine whether it matches that of the key. If the signals are identical the car will be able to unlock itself and start. This is a great way to protect your car from theft.

Transponder keys are an increasingly popular feature in cars, but it is important to know that they're not as secure as classic keys made of metal. The metal portion of a traditional key is easily copied and cut, but the transponder is protected by an electronic chip that guards it. The chip is a unique code which is programmed into a car's computer in order to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. The car can only recognize the key fob if the device has an unmodified chip and has been programmed to match. The car won't start if the key is not programmed to match.

It is vital to have an extra Saab key. This is particularly important for those who live in a rural location that has numerous car thieves. You can purchase a new key for your saab 93 key by visiting the dealership, without having to pay their expensive costs. In most cases, you can have a brand new key made right on the spot at a fraction of the cost you would pay at dealerships.

Wired key

Saab cars are typically delivered with two keys. If you have only one, you should purchase an additional key as quickly as you can. This is because if the key is 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 connecting the wires for columns and row to your microcontroller. This is the toughest component of the project and will require a lot of soldering. There's no standard way to go about it, but you must consider how to program saab 9-3 key fob you will route and solder each column and row. For this keyboard, there are 5 rows and 17 columns. This means there will be 22 microcontroller pins and wires to connect.

After the columns and rows are soldered, it's time to connect them to the key switches. To do this you must place an inverter over each pin on the key switch and then solder it. This will shield the pins from current and prevent them from being shortened. A diode allows current to only flow in only one direction. It features a visual indicator, a black band, that shows which way current will flow.

Sanabria says that a few of the tools sold in auto parts stores, like the Autel MaxiIM IM608PRO and the IM508 will assist customers who are shopping or DIY users to program replacement keys and restore immobilizer data. The tools plug into OBD ports and guide the customer through each step which makes the process much easier than replacing the vehicle's computer.

Jumpstarting the battery

Most people keep a set of jumper cables in their trunk for emergency situations however, jumping a battery on newer vehicles might not be the best idea. These cars have a variety of electronic devices and computers that communicate with each other. A voltage spike when batteries are connected to another one could cause damage to the parts making your car inoperable.

Start the vehicle that is working and allow it to run for approximately two minutes before connecting the cables to the non-working one. Attach the red clip to the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface underneath the vehicle's hood. An engine block is a good option. Don't connect the black cable to the negative terminal of the dead battery because this could trigger an ignition source that ignites gasoline in the engine bay.

Once the cables are connected, start the car and let it run for about five minutes. Then, disconnect the cables in reverse. The battery in your Saab 9-3 will be recharged as you drive. It will take a while for it to return to its original state. It is recommended to purchase a second key fob, when you can. The replacement of the one that works requires the installation and programming of a new computer chip.

Replacement Case

Many saab 9-3 key fob programming owners only have one key for their vehicle and if they lose it, key, it will cost them. The reason is that it's expensive to add a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. It is recommended to have a backup key in the event of theft or any other catastrophe, and the best way is to purchase an extra key as early as you can. But don't buy a used key, even when it's "new." Keys that are claimed-new purchased from third-party sellers won't work and are likely to fail in the crucial moment.

The majority of locksmiths won't be able how to get a saab replacement key help if you have only one working key and the dealer will charge top dollar to replace the computer in your car to make a new replacement. We can reset and reprogram the computer's EEEPROM in order to get it ready to accept a replacement key without having to replace the entire system. This could save you a significant amount of money. It's more affordable than wait until you lose the only key.
