How To Save Money On Saab Ignition Key Replacement
Saab Key Programming
Saab cars that were built prior to 1994 have an immobilizer system based on coded keys. To add an additional key, you need the purchase of a new transponder as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.
The issue is that this could be extremely expensive. You should always keep a spare set of keys on hand.
Transponder key
The transponder keys are keys with an electronic chip that transmits a signal to the car when it is inserted into the ignition. The car is able to check whether the signal matches with the one on the key. If the signals are the same the car will be able to unlock itself and begin. This is a great method to stop car theft and keep your vehicle secure from thieves.
Transponder keys are an increasingly popular feature in cars, but it is important to know that they are not as secure as traditional keys made of metal. The metal component of the traditional key can be easily cut and copied, however transponders are protected by an electronic chip that safeguards it. The chip has a unique code that's programmed into a car's computer order to identify it.
The car will recognize the Saab keyfob and permit it to turn on. However, it will only do this if the key fob is equipped with a chip that is not modified that has been programmed to match it. The car won't start in the event that the key has not been programmed to match.
It is crucial to have a spare Saab key. This is particularly true especially if you live in a rural area with many car thieves. You can obtain a replacement key for your Saab by visiting the dealership without paying their high cost. You can get a replacement key created on the spot for less than half of what you would spend at the dealership.
Wired key
Saab cars are usually delivered with two keys. If you have only one, it's best to acquire an extra key fob as soon as you can since if you lose it, your car will require a new CIM unit, and the locking cylinders will need to be replaced. This can be costly particularly if you are buying a second-hand car.
The next step is to connect the wires of columns and row to your microcontroller. This is the most challenging part of the project and requires a significant amount of soldering. It's not a standard way to go about it, but you should determine how to route and connect each column and row. There are 22 microcontroller wires and pins that you can connect for this keyboard. It includes 5 rows and 17 columns.
Once the rows and columns are soldered, it's the time to connect them to key switches. To do this you must place a diode on each pin on the key switch and then solder it. saab replacement keys uk G28 Car Keys will shield the pins on the key switch from current and keep them from being shorted. The diode allows current to only flow in only one direction. It features a visual indicator of a black line that shows which way current will flow.
A few of the tools that are available at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- may help customers in the shop, or even DIY users in some cases programme replacement keys and recover lost immobilizer data Sanabria says. The tools plug into OBD ports and help the customer through each step making the process simpler than replacing the car's computer.
Jumpstarting the battery
The majority of people have an item in their trunk to jump-start their vehicle in an emergency, but this might not be a good idea for newer cars. These vehicles have many electronic devices and computers that communicate with each other. A voltage surge when the battery is connected another battery could damage the components, rendering your car undriveable.
Start the working vehicle and allow it to run for approximately two minutes before you connect the cables to the battery that is not working. Attach the red clip on the positive terminal of the battery that is good. (It will read "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface under the disabled vehicle's hood. An engine block is a good choice. The black cable is not to be connected to the negative terminal of the dead battery. This could result in sparks, which would ignite gasoline in the engine compartment.
After the cables have been connected, you need to start the car and let it run for approximately five minutes. Then, disconnect the cables in reverse. Be aware that the battery in your Saab 9-3 is charged during your drive, which means it can take a while for the battery to go back down again. It's a good idea to purchase a spare fob as soon as you can, because replacing the sole working one requires the installation of a new computer module and special programming to convince it that your missing keys aren't trying to steal the car.
Replacement case
Many Saab owners have only one key for their car and if they lose that they'll be charged. The reason for this is that it's costly to add a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft or any other catastrophe, it is best to have an extra key. Even it's "new" it will not function.
The dealer will charge you top dollar if you have only one working key. However, we can reset and reprogram the computer's EEPROM to prepare it to accept the new key, without replacing the whole system. This can save you a lot of money. It's more affordable rather than wait until you lose the only key.
