How To Save Money On Saab Ignition Key Replacement

Saab Key Programming

Saab cars made since 1994 feature an immobilizer mechanism based on coded keys. A new transponder is required for addition of an extra key, and special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.

This can be expensive. It is recommended to always have a spare set of keys in your possession.

Transponder key

The transponder key is a piece of hardware with an electronic chip that transmits a signal to the car when it is inserted into ignition. The car will then check the signal to determine whether it is identical to the one on the key. If both signals match, the car will unlock itself and begin. This is a great way to safeguard your car from theft.

Transponder keys are an increasingly popular feature in automobiles, but you should be aware they are not as secure as traditional metal keys. While the metal component of a traditional key may be cut and copied the transponder is protected by an electronic chip. The chip is a unique code which is programmed into a car's computers in order to identify it.

When a saab key programmer 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 reject the key and won't start.

It is vital to have a spare Saab key. This is particularly important for those who live in a rural region that has many car thieves. The good news is that you can obtain a replacement key for your Saab without having to go to an auto dealership and pay the expensive prices they ask. You can have a replacement key created on the spot at a fraction of the price you'd spend at a dealership.

Key for Wired

saab 9-3 key cars usually come with two keys upon purchase. If you have only one, it's a good idea to get an extra key fob as soon as is possible since if you lose it, your car will require the replacement of a CIM unit and the locking cylinders need to be replaced. This can be costly especially if you're purchasing a used vehicle.

The next step is to connect the column and row wires to the microcontroller. This is the most challenging part of the project and will require a great amount of soldering. There's no standard way to accomplish this, however it is important to think about the route you'll take and solder the rows and columns. For this keyboard, there are five rows and 17 columns. So there will be 22 microcontroller pins and wires to connect.

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

Some of the tools you can find at auto parts stores -like 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 customer through each step and make the process more straightforward than replacing the car's computer.

Jump-starting the battery

The majority of people have the set in their trunk to jump start a vehicle in an emergency, but it may not be a good option for vehicles with newer technology. These vehicles are equipped with numerous digital and computers that communicate with each other. A voltage surge when a battery is connected to another could cause damage to the components, rendering your car undriveable.

Connect the cables to the vehicle that is operating. Allow it to run for two minutes. Attach the red clip on the positive terminal of the battery that is good. (It will read "POS" or "+".) Attach the other end to a clean and unpainted metal surface underneath the hood of the disabled vehicle. The engine block is a good choice. The black cable should not be connected to the negative terminal of the dead battery. This could cause sparks that could ignite gasoline in the engine compartment.

Once the cables are connected, start the disabled vehicle and allow it to run for around five minutes before disconnecting the cables in reverse order. Be aware that the battery in the Saab 9-3 gets recharged while you drive, so it will take a while for the battery to go back to its original level. It is a good idea to invest in a spare key fob as soon as you can, since replacing the only working one requires the installation of a new computer module and special programming to convince it that your missing keys are not trying to steal the car.

replacement key for saab 93 Case

Saab owners often only have one car key, and if it is lost, they will be charged. It's costly to add keys and will require replacing the CIM or TWICE for older models. In the event of theft, or other catastrophe it is recommended to have an extra key. But don't buy a used key, even when it's "new." Keys that are claimed to be new purchased from third-party sellers won't work and are almost guaranteed to fail in the crucial moment.

Most locksmiths can't help you when you only have one working key, and the dealer will charge you top dollar to replace the computer in your vehicle to make a replacement. We can reset and reprogram the computer's EEEPROM in order to be able to accept a replacement key without having to replace the entire system. This can save you a lot of money. It's more affordable instead of waiting until you lose the only key.
