saab 9-3 key not accepted contact service Key Programming

saab 93 key cars made since 1994 feature an immobilizer mechanism based on coded keys. Adding an extra key requires an entirely new transponder and programming. This is usually done by the dealer using a Tech2 diagnostic tool.

The issue is that this can be very costly. This is the reason why you should always have a spare key on hand.

Transponder key

The transponder keys are keys equipped with an electronic chip. It transmits a signal to the car when it is inserted into ignition. The car will then check the signal to determine whether it is the same as the one on the key. If the signals match, the car will unlock and start. This is a great way to deter car theft and keep your car safe from thieves.

Transponder keys are a popular addition to cars, but they are not as secure as traditional keys made of metal. While the metal portion of a conventional key can be cut and copied however, a transponder is secured by an electronic chip. The chip contains a unique code that's programmed into a car's computers in order to identify it.

The car will recognize the saab 93 key fob replacement keyfob, and allow it to turn on. The car will only recognize the key fob if it has a chip that is unmodified and programmed to match. Otherwise, the Car Key Locksmith will reject the key and won't start.

It is essential to ensure that you have a spare key for your saab key programmer. This is particularly true when you live in a rural area with many car thieves. The good part is that you can get a replacement key for your Saab without having to go to an auto dealership and pay the hefty prices they ask. You can get a replacement key for saab 93 key made on the spot for less than half of the price you'd pay at a dealership.

Wired key

Saab cars are usually provided with two keys. If you only have one, you need to purchase an additional key as fast as you can. This is because if you lose it and the car is damaged, it will require a new CIM and the locking cylinders replaced. This can be costly especially if buying a used car.

The next step is to connect the row and columns wires to your microcontroller. This is the most challenging part of the project and will require a great amount of soldering. There is no standard method to accomplish this, but it is crucial to plan the way you'll route and solder the columns and rows. There are 22 microcontroller pins and wires to connect for this keyboard. It includes 5 rows and 17 columns.

After the rows and column are joined then it's time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins from current and prevent them from being shorted. A diode allows current to only flow in only one direction. It features a visual indicator with a black band that shows which way current will flow.

A few of the tools that are available at auto parts stores -- such as the Autel MaxiIM IM608 Pro and IM508 -- could help shop customers or even DIY customers in certain instances create replacement keys and restore lost immobilizer data, Sanabria says. The tools plug into the OBD port and automatically guide the user through the procedure, making it much easier than replacing the computer inside the vehicle.

Jump-starting the battery

The majority of people have an assortment of tools in their trunk to start a car in case of emergency, but it might not be a good idea for newer cars. These vehicles have many digital and computer systems that communicate with each other. A voltage surge while the battery is connected to another can fry the components and render your car unable to drive.

Start the vehicle you are using and allow it to run for around two minutes before you connect the cables to the non-working one. Attach the red clip to the positive terminal of the good battery. (It will say "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface underneath the disabled car's hood. The engine block would be a good option. The black cable should not be connected to the negative terminal of the dead battery. This could trigger a spark, which would ignite gasoline in the engine compartment.

Once the cables are connected, turn on the vehicle that is disabled and let it run for about five minutes before you disconnect the cables in reverse order. The battery in the Saab 9-3 will charge as you drive. It will take a while for it to recharge again. It is recommended to purchase a second key fob, as soon as possible. Replacing the original one that works requires the installation and programming of a brand new computer chip.

Replacement case

Saab owners usually have only one car key, and if that is lost, they'll be charged. The reason for this 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 best to have a backup key in the event of theft or any other catastrophe and the best option is to purchase an extra key as early as you can. Even if the key is "new", it won't work.

The dealer will charge you top dollar if you only have 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 save you a significant amount of money. It's also a lot cheaper than waiting until you lose your only key.
