Description Mercedes EIS (Electronic Ignition Switch) programming/cloning. If you have a faulty EIS, we can clone your EIS to a used EIS. If we provide the donor EIS, we back your cloned EIS with a 2 year warranty. We cannot clone any EIS that has the newest FBS4 encryption. Most models newer than 2015 have FBS4 encryption. Some models have FBS4 encryption starting with year 2012 (W218 W212 W166). Call us if you‘re not sure we can clone your EIS. Send in your original EIS and key for cloning. If you don’t have a key, that’s ok, we can still clone your EIS. We offer lost package insurance for $25. This covers your parts in the event of loss either in transit to us or in transit back to you. With our insurance, you can ship your valuable modules with peace of mind. If you are providing the donor EIS, send it in as well. Benz Tech Modules LLC 13502 Whittier Blvd STE H-504 Whittier CA 90605 Call or text for more information: (818) 510-3375
