Saab Key Programming

Saab cars manufactured since 1994 feature an immobilizer mechanism based on coded keys. In order to add a second key, it requires a new transponder and special programming. This is usually done by the dealer, using a specially-designed Tech2 diagnostic tool.

This can be expensive. It is recommended to always have a spare set of keys on hand.

Transponder key

The transponder key is a key equipped with an electronic chip. It sends a signal back to the car when it is placed in the ignition. The car checks to see whether the signal matches the one on the key. If the signals match the car will be able to unlock itself and begin. This is a great method to avoid auto theft and keep your car safe from thieves.

Transponder keys are a popular addition to cars, but they are not as safe as traditional keys made of metal. The metal part of the traditional keys can be easily cut or copied, while transponders have an electronic chip that guards it. The chip is equipped with an unique code that is encoded into the car's system to identify it.

When a saab 9-3 key replacement ignition key replacement - his response, key fob is used, the car recognizes it and allows it to turn on. The car can only recognize the key fob when it has a chip that is unmodified and programmed to match. Otherwise, the car would refuse to accept the key and will not start.

It is essential to ensure that you have an extra key for your Saab. This is particularly important if you reside in a rural area that is home to numerous car thieves. The good news is that it's possible to find a new key for your saab 9-3 replacement key without needing to visit an auto dealer and pay the high prices they ask. You can have a replacement key made on the spot for less than half what you would pay at an auto dealer.

Key for Wired

Saab cars typically come with two keys when new. If you own only one, you should get an additional key as quickly as you can. This is because if you lose it and the car needs an entirely new CIM and the locking cylinders replaced. This can be costly especially for used vehicles.

The next step is to wire the row and column wires to the microcontroller. This is the most difficult part of the project and will require a large amount of soldering. There's no standard way to accomplish this, however it's important to plan out the route you'll take and solder the columns and rows. There are 22 microcontroller wires and pins to connect for this keyboard. It has 5 rows and 17 columns.

After the columns and rows are soldered, it's time to connect them to key switches. To do this, you need to place a diode over each pin on the key switch and solder it. This will shield the pins from current, preventing them from being shorted. A diode allows current to only flow in only one direction. It is equipped with a visible indicator that is black, that shows the direction in which the current will flow.

Some of the tools you can find at auto parts storeslike 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 information, 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

Most people keep a set in their trunk to jump-start a vehicle in an emergency, but it may not be the best idea for vehicles that are newer. These vehicles are equipped with electronic devices and computers that communicate with one another. A voltage surge when batteries are connected to another one could cause damage to the parts making your car unusable.

Connect the cables to the vehicle 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 to a clean, unpainted metal surface beneath the hood of the damaged vehicle. The engine block is a great choice. The black cable should not be connected to the negative terminal of the dead battery. This could create sparks, which would ignite gasoline in the engine compartment.

Once the cables are connected, start the vehicle you are not using and let it run for approximately five minutes before you disconnect them in reverse order. Keep in mind that the battery on the Saab 9-3 gets recharged during your drive, which means it can take a while to get the battery down. You should purchase an additional key fob as soon as possible. The replacement of the one that works requires the installation and programming of a new computer chip.

Replacement Case

Many Saab owners only have one key for their vehicle and if they lose that they'll be charged. It's expensive to buy a key and requires replacing the CIM or TWICE for older models. It is recommended how to get a saab replacement key have a backup key in the event of theft or other disaster, and the best way is to purchase an extra key as soon as you are able to. Even it's "new", it will not work.

The dealer will charge you top dollar for only one working key. However, we can reset and re-program the computer's EEPROM to accept an alternative key without replacing the entire system. This can help you save a significant amount of money. It's also a lot cheaper than waiting until you lose your sole key.
