14 Questions You're Anxious To Ask Saab Ignition Key Replacement
Saab Key Programming


Saab cars that were built prior to 1994 have an immobilizer feature built on coded keys. To add an additional key, you need a new transponder, as well as special programming. This is usually done by the dealer using a special Tech2 diagnostic tool.

It can be costly. This is the reason why you should always have a spare key available.

Transponder key

The transponder is a key equipped with an electronic chip. This chip sends out a signal when the key is put into the ignition. The car is able to check whether the signal is the same as the one on the key. If the signals match, the car will unlock and start. This is a great method to avoid car theft and keep your vehicle safe from thieves.

Transponder keys are an increasingly popular feature in vehicles, but you must be aware that they aren't as secure as classic keys made of metal. The metal component of the traditional key can be easily cut and copied, however a transponder has an electronic chip that safeguards it. This chip contains a unique code that is programmed into the car's computers to identify it.

The car will recognize the Saab keyfob and permit it to be turned on. However, it will only do this if the key fob is unmodified and has a chip that has been programmed to match the original. The car won't start in the event that the key has not been programmed to match.

It's crucial to ensure that you have an extra key for your Saab. This is especially true if you live in a rural location where there are many car thieves. The good news is that it's possible to find a replacement key to your Saab without having to go to a dealership and pay the high costs that they charge. You can get a replacement key created on the spot for less than half of the cost you would spend at a dealership.

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 is possible as if you lose it, the car will require the replacement of a CIM unit and the locking cylinders will have to be replaced. This can be costly, especially for used cars.

The next step is to wire the wires of the column and row to the microcontroller. This is the most tedious part of the project and will require lots of soldering. The Key Lab 's not a standard way to do it, but you need to plan how to route and connect each column and row. There are 22 microcontroller wires and pins that you can connect for this keyboard. It has five 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, put an inverter over each pin of the key switch and 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 an indicator in black that indicates which way the current will flow.

Some of the tools offered at auto parts stores- such as the Autel MaxiIM IM608 Pro and IM508 -- could help customers in the shop, or even DIY customers in some cases programme replacement keys and recover the lost immobilizer's data, Sanabria says. The tools connect to OBD ports and guide the user through each step, making the process easier than replacing the vehicle's computer.

Jumpstarting the battery

A lot of people keep a set of jumper cables in their trunk for emergency situations however, jumping a battery on newer vehicles may not be the best option. These cars have a variety of digital and computer systems that communicate with one another. A surge in voltage when a battery is hooked up to another could cause damage to these components and render your car unable to drive.

Start the vehicle that is working and let it run for about two minutes before you connect the cables to the disabled one. Attach the red clip on the positive terminal of the good battery. (It will read "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface underneath the 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 spark a spark that ignites the gasoline in the engine bay.

After the cables have been connected, you should start the car and let it run about five minutes. Then, disconnect the cables in reverse. Keep in mind that the battery on your Saab 9-3 is recharged during your drive, which means it will take a while to get the battery back down again. It's a good idea purchase a spare key fob as soon as you can, because replacing the one that works requires the installation of a brand new computer module and special programming to convince it that the lost keys are not trying to steal the car.

Replacement Case

Many Saab owners only have one key for their vehicle and if they lose that key, it will cost them. It's expensive to purchase keys and will require replacing the CIM or TWICE in the case of older models. It's recommended to have a second key in case of theft or any other catastrophe, and the best way is to purchase an additional key as soon as you can. Don't purchase a used key, even if it's "new." Keys that are claimed to be new purchased from third-party sellers won't be effective and are almost guaranteed to fail in the most critical moment.

The dealer will charge the highest dollars if you only have one working key. We can reset and reprogram the computer's EEEPROM in order to make it ready to accept a new key without the need to replace the entire system. This can save you a lot of money. It's less expensive than wait until you lose your only key.
