Saab Key Programming

saab 93 replacement key cars made since 1994 feature an immobilizer mechanism made up of coded keys. To add an additional key, you need a new transponder and special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.

The issue is that this could be extremely expensive. Always keep an extra set of keys on hand.

Transponder key

The transponder is a type of key equipped with an electronic chip. This chip sends a signal when the key is put in the ignition. The car then checks to see whether the signal is the same as the one on the key. If the signals are in sync then the car will be able to unlock and start. This is a great way to stop auto theft and keep your vehicle secure from thieves.

Transponder keys are a popular feature in automobiles, however it is important to know that they're not as secure as traditional metal keys. The metal component of a traditional key can easily be cut and copied, whereas transponders are protected by an electronic chip that protects it. The chip has a 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, it's only able to do so if the key fob is unmodified and has a chip that has been programmed to match it. Otherwise, the car would reject the key and won't start.

It's essential to ensure that you have a spare key for your Saab. This is particularly important if you live in a rural area where there are many car thieves. The good thing is that you can obtain a replacement key for your saab 93 key replacement without having to go to an auto dealer and pay the high costs that they demand. In most cases, you can have an original key made on the spot for less than half the cost of what you would pay at dealerships.

Key for Wired

saab 93 replacement key cars are usually delivered with two keys. If you only have one, it is recommended to get an additional key as quickly as you can. This is because, if it's lost and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This could be expensive especially if you're purchasing a used vehicle.

The next step is to wire the row and column wires to the microcontroller. This is the most challenging part of the project and requires a significant deal of soldering. There is no standard method to do this, but it is crucial to plan the routes you'll use to solder the columns and rows. For this keyboard, there are five rows and 17 columns. This means there will be 22 microcontroller wires and pins that you need to connect.

After the columns and rows are joined, it is time to connect the key switches. To do this, place a diode over each key switch pin and then solder it. This will shield the pins of the key switch from current and keep them from being shorted. The diode allows current to only flow in one direction. It features a visual indicator that is black, that shows the direction in which the current will flow.

Some of the tools offered at auto parts stores -- such as the Autel MaxiIM IM608 PRO and IM508 -- may assist customers at the shop or DIY customers in some cases program replacement keys and restore the lost immobilizer's data, Sanabria says. The tools plug into the OBD port and guide the user through the process, making it more simple than replacing the computer in the vehicle.

Jump-starting the battery

A majority of people keep the set in their trunk to jump start a car in case of emergency, but this might not be a good option for vehicles with newer technology. These cars are equipped with a variety of digital and computer systems that communicate with one another. A voltage surge while a battery is hooked up to another could cause damage to the components and render your vehicle undriveable.

Connect the cables to the vehicle that is operating. Allow it to run for two minutes. Attach the red clip to the positive terminal of the battery that's good. (It will read "POS" or "+".) Attach the other end to a clean, unpainted metal surface beneath the hood of the disabled car. The engine block is an excellent option. 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 in the engine compartment.

Once the cables are connected, you need to start the car and let it run for about five minutes. Then disconnect them in reverse. The battery in your saab key fob repair 9-3 is recharged as you drive. It may take a while it to drop back down. It is recommended to purchase a second key fob, as soon as you can. Replacing the only 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 will be charged. It's expensive to add an additional key and it requires replacing the CIM or TWICE for older models. In the event of theft, or any other calamity it is recommended to have a spare key. But don't buy a used key even it's "new." Keys that are claimed-new from a second-hand store will not be effective and are almost guaranteed to fail at the crucial moment.

The dealer will charge you top dollar for only one working key. However, we can reset and re-program the computer's EEPROM in order to prepare it to accept a new key without replacing the whole system. This could save you lots of money. It's much cheaper rather than wait until you lose the only key.
