In this article,car-auto-repair.com show you guide on how to use BMW Rheingold ISTA software perform Vehicle and Key Memory programming.
What is Vehicle and Key Memory (CKM)?
On customer request, various vehicle settings can be changed by means of coding on certain E-model series (e.g. E46, E6X). Some settings (Key) are allocated to a certain key (max. four keys), e.g. heating/air conditioning/ventilation while other settings (Vehicle) apply globally to the entire vehicle, e.g. antitheft alarm system.
Vehicle and Key Memory settings can be selected under the “CKM” tab after determining the native measures plan in the “Vehicle” menu.
Due to different legal stipulations, there may be national differences in possible CKM settings. Factory settings may also vary from country to country.
When replacing control modules, it may happen that individual data in the CKM settings are not automatically restored. Before replacing a control module, the CKM settings in the vehicle must be printed out so that these can be restored after the control module has been replaced.
BMW E70, E71, E81, E82, E87, E88, E90, E91 E92, E93, F01 F02 MINI R55 and R56
On these model series, all Vehicle and Key Memory functions are programmed directly in the vehicle (please refer to “Personal Profile” in the Owner’s Manual: individual settings for a maximum of 3 remote control units via the display in the instrument cluster or via the Central Information Display).
BMW E38, E39, E46, E52, E53, E60, E61, E63, E64, E65, E66, E83, E85 and E86 MINI R50, R52 and R53 Rolls-Royce
The procedure for programming the Vehicle and Key Memory is described below. The basic prerequisite is that all control modules on a vehicle are programmed to the current software status:
Two or more parameter keywords (e.g. active, inactive) are assigned to a function or a function keyword. The current setting is shown by a selected checkbox next to the parameter keyword and can be changed by the service technician. Key functions can be set individually for the max. 4 keys. The factory setting is represented by a corresponding symbol next to the parameter keyword.
The CKM functions are divided into a maximum of three levels of hierarchy. Main group (e.g. central locking), group (e.g. unlocking rear window, boot/rear lid) and an optional subgroup (e.g. lids after ignition on).

1 “CKM” tab
2 “Vehicle” menu
3 Symbol for “Factory settings”,shows the factory setting of the function
4 Tick – the green tick shows the selected setting of the function,the gray tick shows the active setting of the function
5 “Factory settings” button,establishes the factory settings for the vehicle and keys
6 “Cancel all” button,cancels all settings
7 “Determine measures plan” button
You can print out the set CKM values. Printing out the CKM settings could cause values that have been entered in the list but not yet stored in the vehicle to be lost,making it necessary to re-enter them. It is advisable to print out the CKM settings at the start of programming and if necessary immediately after completing CKM reprogramming.
Procedure for changing CKM settings
The selected settings for the Vehicle and Key Memory are retained even when the control modules are reprogrammed or encoded. If the CKM backup or restore cannot be successfully performed, this will be seen in the final report.
